Isotropic Composite(各向同性复合材料)研究综述
Isotropic Composite 各向同性复合材料 - 9% increase in energy absorption is achieved by the quasi-isotropic composites comparing with the orthotropic composites under the same areal density, caused by enlarged stress dissipation and deformation areas as the yarn directions increase. [1] Remarkably, experimental results demonstrate that by exciting such anisotropic composites along the alignment direction enhances the LFIH effect by more than 30%. [2] The paper introduces an approximate method for computing the effective conductivity of isotropic composites with imperfect interfaces in two-dimensional space. [3] Experimental results validated the feasibility of the developed acoustic field-assisted TPP process on printing anisotropic composites with spatially controlled material compositions. [4] Herein, we investigate the electrical resistance relaxation of anisotropic composites when they are subjected to an external electric field. [5] A hybrid model of nonlinear homogenisation of anisotropic composites was developed, based on the secant Eshelby's model of the second order. [6] This analysis is necessary for the creation of anisotropic composites that are sensitive to external stimuli. [7] For a certain kind of shale or tight sandstones, which are viewed as isotropic composites, both the models work well. [8] Elastic modulus measurements of anisotropic composites under a magnetic field suggest that NBR composites have much better field-dependent magnetic properties than NR composites. [9] The results show that the resistive loss dominates the eddy current attenuation in less conductive and high anisotropic composites, resulting in a frequency independent attenuation law, which is very different from skin effect. [10] In this research, we applied a polynomial hybrid approach for modelling longitudinal guided waves propagating in anisotropic composites multi-layered pipes. [11] 5 wt%, which is over 3 times that of the isotropic composite with the same BN content. [12] The anisotropic composites damage evolution was characterized by Murakami-Ohno damage theory. [13] Due to extensive applications in engineering practice, analysis of heat transfer in three-dimensional anisotropic composites has remained to be an important research topic. [14] Our work mainly researches the high-precision calculation model of equivalent permittivity of anisotropic composites based on machine learning. [15] Based on the understanding of this principle, a clever approach for a hidden code could be proposed which is obtained from mixing pure iron oxide and silica coated microrod supraparticles in such an anisotropic composite. [16] The obtained results in this paper can be applied to design the fiber-reinforced anisotropic composites under thermal load to satisfy some particular engineering requirements. [17] In a previous work, a very promising mathematical model for predicting the electrical conductivity below the electrical percolation threshold, for both isotropic and anisotropic composites, was pub. [18] A method is proposed for generating reliable representative volume elements (RVEs) that allows reducing the statistical analysis required for the simulation of the mechanical behavior of isotropic composites highly filled with monosized spheres. [19] Past work has shown that thermally anisotropic composites (TACs) can be created by the alternate layering of two dissimilar, isotropic materials. [20] Correction for 'High piezo-resistive performances of anisotropic composites realized by embedding rGO-based chitosan aerogels into open cell polyurethane foams' by Tianliang Zhai et al. [21] In particular the multiscale strategy is proposed for deriving the constitutive relations of anisotropic composites with periodic microstructure and allows us to reduce the typically high computational cost of fully microscopic numerical analyses. [22] In this work, an anisotropic composite is fabricated by wet 3D printing of epoxy crosslinked chitosan/carbon microtubes. [23] Most aerogels are isotropic, thus leading to isotropic composites when they are used as fillers. [24] The quasi-isotropic composite has the smallest induced damage and the highest peak load. [25] In addition, the design result of anisotropic composite is compared with the isotropic multi-material design result to validate the benefit of anisotropic composite in actuators. [26] The feasible method to solve stress-field problems in anisotropic composites is to use complex analytic function theory, and the results have been reported [6]. [27] No analytical solution exists for predicting dispersion in highly anisotropic composites. [28] The method combines a quantitative wavefront expression for an anisotropic composite and the conventional time-of-flight (ToF) method to detect debonding damage between stiffeners and the composite skin as well as low-velocity impact damage in the skin sheet. [29] The porosity provides a meaningful model for the thermal shock damage evolution in the anisotropic composites. [30] Industrial printed circuit boards (PCBs) are nonhomogeneous and anisotropic composites consisting of copper traces, glass-reinforced epoxy laminate (FR-4), solder mask, vias, and other features. [31] This article proposes an efficient computational methodology for evaluation of two-dimensional interlaminar stresses in thin anisotropic composites subjected to inertial loads. [32] The only viable method to solve the stress boundary problems in anisotropic composites may be to use the complex analytic function theory, and the results have been reported [9~12]. [33]与相同面密度下的正交各向异性复合材料相比，准各向同性复合材料的能量吸收增加了 9%，这是由于随着纱线方向的增加应力消散和变形区域扩大所致。 [1] 值得注意的是，实验结果表明，通过沿排列方向激发这种各向异性复合材料，可以将 LFIH 效应提高 30% 以上。 [2] 介绍了一种计算二维空间中界面不完善的各向同性复合材料有效电导率的近似方法。 [3] 实验结果验证了开发的声场辅助 TPP 工艺在打印具有空间受控材料成分的各向异性复合材料上的可行性。 [4] 在此，我们研究了各向异性复合材料在外电场作用下的电阻弛豫。 [5] 基于二阶割线 Eshelby 模型，开发了各向异性复合材料非线性均质化的混合模型。 [6] 这种分析对于创建对外部刺激敏感的各向异性复合材料是必要的。 [7] 对于被视为各向同性复合材料的某种页岩或致密砂岩，这两种模型都运行良好。 [8] 磁场下各向异性复合材料的弹性模量测量表明，NBR 复合材料比 NR 复合材料具有更好的磁场相关磁性。 [9] 结果表明，在低导电性和高各向异性复合材料中，电阻损耗在涡流衰减中占主导地位，导致与频率无关的衰减规律，这与趋肤效应有很大不同。 [10] 在这项研究中，我们应用多项式混合方法来模拟在各向异性复合材料多层管道中传播的纵向导波。 [11] 5 wt%，是相同 BN 含量的各向同性复合材料的 3 倍以上。 [12] 利用 Murakami-Ohno 损伤理论对各向异性复合材料的损伤演化进行了表征。 [13] 由于在工程实践中的广泛应用，三维各向异性复合材料的传热分析一直是一个重要的研究课题。 [14] 我们的工作主要研究基于机器学习的各向异性复合材料等效介电常数的高精度计算模型。 [15] 基于对这一原理的理解，可以提出一种巧妙的隐藏代码方法，该方法是通过在这种各向异性复合材料中混合纯氧化铁和二氧化硅涂覆的微棒超粒子获得的。 [16] 本文获得的结果可用于设计热负荷下的纤维增强各向异性复合材料，以满足某些特定的工程要求。 [17] 在以前的工作中，一个非常有前途的数学模型用于预测低于电渗流阈值的电导率，对于各向同性和各向异性复合材料，是 pub。 [18] 提出了一种生成可靠的代表体积元素 (RVE) 的方法，该方法允许减少模拟高度填充单一尺寸球体的各向同性复合材料的力学行为所需的统计分析。 [19] 过去的工作表明，热各向异性复合材料 (TAC) 可以通过两种不同的各向同性材料的交替分层来制造。 [20] Tianliang Zhai 等人对“通过将 rGO 基壳聚糖气凝胶嵌入开孔聚氨酯泡沫中实现的各向异性复合材料的高压阻性能”的校正。 [21] 特别是提出了多尺度策略来推导具有周期性微观结构的各向异性复合材料的本构关系，并允许我们降低全微观数值分析的典型高计算成本。 [22] 在这项工作中，通过湿法 3D 打印环氧交联壳聚糖/碳微管来制造各向异性复合材料。 [23] 大多数气凝胶是各向同性的，因此当它们用作填料时会产生各向同性的复合材料。 [24] 准各向同性复合材料具有最小的诱导损伤和最高的峰值载荷。 [25] 此外，将各向异性复合材料的设计结果与各向同性多材料设计结果进行比较，以验证各向异性复合材料在执行器中的优势。 [26] 解决各向异性复合材料应力场问题的可行方法是使用复解析函数理论，其结果已被报道[6]。 [27] 不存在用于预测高度各向异性复合材料中的色散的解析解。 [28] 该方法结合了各向异性复合材料的定量波前表达式和传统的飞行时间 (ToF) 方法来检测加强筋和复合蒙皮之间的脱粘损伤以及蒙皮中的低速冲击损伤。 [29] 孔隙率为各向异性复合材料的热冲击损伤演化提供了一个有意义的模型。 [30] 工业印刷电路板 (PCB) 是非均质和各向异性复合材料，由铜迹线、玻璃增强环氧树脂层压板 (FR-4)、阻焊层、通孔和其他特征组成。 [31] 本文提出了一种有效的计算方法，用于评估承受惯性载荷的薄各向异性复合材料中的二维层间应力。 [32] 解决各向异性复合材料中应力边界问题的唯一可行方法可能是使用复解析函数理论，其结果已被报道[9~12]。 [33]

A series of drop tower low-velocity impact tests were performed on quasi-isotropic composite plates. [1] Quasi-isotropic composite laminates were subjected to low-velocity impact energy ranging from 2J to 4. [2] In order to elucidate the hygroscopic effects on impact-resistance of carbon fiber/epoxy quasi-isotropic composite plates, low-velocity impact tests are conducted on dry and hygroscopically conditioned plates, respectively, under identical configurations.

Transversely Isotropic Composite
The object of the research was a unidirectional transversely isotropic composite with a two-phase polydisperse structure - a piezo actuator cell and fragments of polydisperse fibrous structures. [1] When both the matrix and the fibers are isotropic, for the 2D fiber distributions at least three direction arrangements of fibers are needed to build the fiber-reinforced transversely isotropic composite materials, and for the 3D fiber distributions at least six direction arrangements are needed to build the fiber-reinforced isotropic composite materials. [2] This paper develops a micropolar constitutive model for a transversely isotropic composite material comprised of a polymer matrix and unidirectional fibers. [3] In this paper, the strength and deformation behavior of transversely isotropic composite rock-like material, which consists of a hard rock-like material and a weak rock-like material, are first investigated under different confining pressures by using a rock triaxial testing system. [4] Failure initiation is predicted with state of the art failure criteria for transversely isotropic composite materials. [5] To illustrate the new constitutive equations, strain energy density functions in terms of the distortion tensor are provided for unconstrained and incompressible isotropic materials, incompressible transversely isotropic composite materials, and incompressible orthotropic composite materials with two families of fibers. [6] A discrete element (DE) model is developed to simulate, with low computational effort, the propagation of solitary waves in a linear array of spherical particles as well as their interaction with a transversely isotropic composite beam. [7]nan [1] 当基体和纤维均为各向同性时，对于 2D 纤维分布，至少需要三个方向排列的纤维来构建纤维增强横向各向同性复合材料，对于 3D 纤维分布，至少需要六个方向排列来构建纤维增强各向同性复合材料。 [2] 本文开发了一种由聚合物基体和单向纤维组成的横向各向同性复合材料的微极本构模型。 [3] 本文首先利用岩石三轴试验系统研究了由硬质类岩材料和弱类类岩材料组成的横向各向同性复合类岩材料在不同围压下的强度和变形行为。 [4] 使用横向各向同性复合材料的最新失效标准预测失效开始。 [5] 为了说明新的本构方程，我们为无约束和不可压缩各向同性材料、不可压缩横向各向同性复合材料和不可压缩正交各向同性复合材料提供了以畸变张量表示的应变能密度函数。 [6] 开发了一个离散元 (DE) 模型，以低计算量模拟孤立波在球形粒子线性阵列中的传播以及它们与横向各向同性复合光束的相互作用。 [7]

For anisotropic composite material cases, directivity plots can be extracted, containing the phase-velocities, group velocities, and slowness curves. [1] The paper shows the results of research on the stress-strain behavior of anisotropic composite materials in the structures of wood-metal slide bearings. [2] This opens up prospects for the use of anisotropic composite materials to ensure the thermal regime of the nanosatellite. [3] ” Step deformation is the main mechanism of deformation and destruction of anisotropic composite materials upon impact. [4] However, the structural response of shear walls reinforced with non-isotropic composite material nets, bonded with relatively low-strength and non-elastic mortar matrices is difficult to study with numerical models. [5] In what follows, we develop a coupled chemo-mechanical model to predict the oxidation response of this highly anisotropic composite material, based on an earlier developed multiphysics theory of bulk polymer’s oxidation. [6] Modern technology shows increased demands on the strength properties of machines, their parts, as well as various structures, reducing their weight, volume and size, which leads to the need to use anisotropic composite materials. [7] Technique of determination of permissible compressive stresses in products made of anisotropic composite materials with holes in joints “parent sheet - stiffening element” is introduced. [8] The modified representations are used to derive closed-form expressions for the local elastic fields and effective moduli of a macroscopically isotropic composite materials containing spherical and circular inhomogeneities with the interfaces described by the complete Gurtin-Murdoch and Steigmann-Ogden models. [9] However, bone is an anisotropic composite material made by mineral, proteins and water assembled in a hierarchical structure. [10] When both the matrix and the fibers are isotropic, for the 2D fiber distributions at least three direction arrangements of fibers are needed to build the fiber-reinforced transversely isotropic composite materials, and for the 3D fiber distributions at least six direction arrangements are needed to build the fiber-reinforced isotropic composite materials. [11] This paper develops a micropolar constitutive model for a transversely isotropic composite material comprised of a polymer matrix and unidirectional fibers. [12] For enhancing the chatter stability, using anisotropic composite materials in the preparation of boring bars proves to be an effective method so as to enhance the boring bar’s natural frequency and damping. [13] In many aerospace and mechanical applications, wings and rotor blades present complex geometric shapes and are made of advanced, highly anisotropic composite materials. [14] Anisotropic composite materials can be divided into three different fiber reinforcements, namely synthetic, natural, and hybrid fibers. [15] The effect of components of the thermal conductivity tensor of heat-protection material on heat fluxes from the gas to the body were studied based on the first obtained analytical solution of the problem of heat transfer in anisotropic composite material in conditions of a convective-conductive heat transfer flow around by a high-temperature gasdynamic boundary layer. [16] The applicability of both methods was further proven by analyzing the isotropic composite materials, a process involving the use of iron particles embedded in a dielectric matrix. [17] Failure initiation is predicted with state of the art failure criteria for transversely isotropic composite materials. [18] To illustrate the new constitutive equations, strain energy density functions in terms of the distortion tensor are provided for unconstrained and incompressible isotropic materials, incompressible transversely isotropic composite materials, and incompressible orthotropic composite materials with two families of fibers. [19] This paper presents a topology optimization method which is capable of designing both topology and orientation distribution of anisotropic composite material simultaneously. [20] This paper presents a fast numerical approach to optimize the localization of induced power in highly anisotropic composite materials with a large scale factor. [21] Design rules were developed for the optimization of anisotropic composite materials. [22]对于各向异性复合材料情况，可以提取方向图，其中包含相速度、群速度和慢度曲线。 [1] 本文展示了各向异性复合材料在木质金属滑动轴承结构中的应力-应变行为研究结果。 [2] 这为使用各向异性复合材料确保纳米卫星的热状态开辟了前景。 [3] ” 阶跃变形是各向异性复合材料在冲击时变形和破坏的主要机制。 [4] 然而，用非各向同性复合材料网加固的剪力墙的结构响应，用相对低强度和非弹性砂浆基质粘合，很难用数值模型研究。 [5] 在下文中，我们基于早期开发的本体聚合物氧化的多物理场理论，开发了一个耦合化学-机械模型来预测这种高度各向异性复合材料的氧化响应。 [6] 现代技术对机器及其零件以及各种结构的强度性能的要求越来越高，减少了它们的重量、体积和尺寸，这导致需要使用各向异性复合材料。 [7] 介绍了“母板-加劲元件”接头中开孔的各向异性复合材料制品的许用压应力测定技术。 [8] 修改后的表示用于导出宏观各向同性复合材料的局部弹性场和有效模量的封闭形式表达式，该复合材料包含球形和圆形不均匀性，具有完整的 Gurtin-Murdoch 和 Steigmann-Ogden 模型描述的界面。 [9] 然而，骨是一种由矿物质、蛋白质和水以分层结构组装而成的各向异性复合材料。 [10] 当基体和纤维均为各向同性时，对于 2D 纤维分布，至少需要三个方向排列的纤维来构建纤维增强横向各向同性复合材料，对于 3D 纤维分布，至少需要六个方向排列来构建纤维增强各向同性复合材料。 [11] 本文开发了一种由聚合物基体和单向纤维组成的横向各向同性复合材料的微极本构模型。 [12] 为了提高颤振稳定性，在镗杆制备中使用各向异性复合材料被证明是提高镗杆固有频率和阻尼的有效方法。 [13] 在许多航空航天和机械应用中，机翼和转子叶片呈现出复杂的几何形状，并由先进的高度各向异性的复合材料制成。 [14] 各向异性复合材料可分为三种不同的纤维增强材料，即合成纤维、天然纤维和混合纤维。 [15] 在首次获得对流-传导热条件下各向异性复合材料传热问题的解析解的基础上，研究了热保护材料的热导张量分量对从气体到机体的热通量的影响。通过高温气体动力学边界层转移流动。 [16] 通过分析各向同性复合材料进一步证明了这两种方法的适用性，该过程涉及使用嵌入介电基质中的铁颗粒。 [17] 使用横向各向同性复合材料的最新失效标准预测失效开始。 [18] 为了说明新的本构方程，我们为无约束和不可压缩各向同性材料、不可压缩横向各向同性复合材料和不可压缩正交各向同性复合材料提供了以畸变张量表示的应变能密度函数。 [19] nan [20] nan [21] nan [22]

[2] 7 mm, and compared it with the behavior of continuous fiber quasi-isotropic composite laminate with a similar plate thickness. [3] Quasi-isotropic composite laminates were subjected to low-velocity impact energy ranging from 2J to 4. [4] In this paper, numerical model based on continuum damage mechanics is presented to predict the damage behavior in quasi-isotropic composite laminates under low-velocity impact conditions. [5] This research presents a numerical method to analyze the propagation characteristics of guided waves in multi-layered anisotropic composite laminates. [6] The paper deals with the determination of effective material parameters of anisotropic composite laminate structures using ultrasonic surface acoustic waves. [7]这种方法最终通过各种各向异性复合层压板的模态分析得到验证。 [1] 对带有预制表面裂纹的CCF300/5228A准各向同性复合层合板的压缩破坏行为进行了实验研究。 [2] 7 mm，并将其与具有相似板厚的连续纤维准各向同性复合层压板的行为进行了比较。 [3] 准各向同性复合材料层压板经受 2J 到 4 的低速冲击能量。 [4] 本文提出了基于连续损伤力学的数值模型来预测准各向同性复合材料层合板在低速冲击条件下的损伤行为。 [5] 本研究提出了一种数值方法来分析导波在多层各向异性复合层压板中的传播特性。 [6] 本文涉及使用超声波表面声波确定各向异性复合层压结构的有效材料参数。 [7]

A series of drop tower low-velocity impact tests were performed on quasi-isotropic composite plates. [1] In this work, we studied the scattering behavior of an incident A0 guided wave mode propagating towards an impacted damaged zone created within a quasi-isotropic composite plate. [2] In this method, pure SH0 wave excitation was achieved using the adjustable angle beam transducers (ABT) in quasi-isotropic composite plates. [3] In order to elucidate the hygroscopic effects on impact-resistance of carbon fiber/epoxy quasi-isotropic composite plates, low-velocity impact tests are conducted on dry and hygroscopically conditioned plates, respectively, under identical configurations. [4] Due to wide application of anisotropic composite plates in modern engineering structures and they were studied rare in literature, the main goal of this work is to study dynamic stability analysis of general anisotropic composite plates. [5] It is thus proposed in this paper to investigate strategies for the spatial integration of common baseline-free methods (namely BI and RR) on an experimental case of damage on a highly anisotropic composite plate. [6] Experiments were conducted on cross-ply and quasi-isotropic composite plates with identical boundary conditions. [7]对准各向同性复合板进行了一系列落塔低速冲击试验。 [1] 在这项工作中，我们研究了入射 A0 导波模式向准各向同性复合板内产生的冲击损伤区传播的散射行为。 [2] 在该方法中，使用准各向同性复合板中的可调角度波束传感器 (ABT) 实现了纯 SH0 波激发。 [3] nan [4] 由于各向异性复合板在现代工程结构中的广泛应用和文献研究较少，本工作的主要目的是研究一般各向异性复合板的动力稳定性分析。 [5] 因此，本文提出在高度各向异性复合板损伤的实验案例中研究常用无基线方法（即 BI 和 RR）的空间整合策略。 [6] nan [7]

Anisotropic composite films of polyaniline (PANI) with single-walled carbon nanotube (SWCNT) were prepared by in-situ electro-polymerization on highly oriented high density polyethylene (HDPE) films. [1] Further, anisotropic composite films exhibited in-plane thermal conductivity as high as ∼3. [2] This facile strategy should be applicable to other natural or synthetic polymers to fabricate anisotropic composite films with potential applications as optical devices, sensors, and actuators. [3] The influence of organoclays on the mechanical properties and drawability of these isotropic composite films was investigated.
