## What is/are Impact Problem?

Impact Problem - Numerical results show that the model smoothing method is a new effective approach for the numerical analysis of contact-impact problems in flexible multibody system.^{[1]}In addition to experimental validation, the FEM model is validated by comparing the numerical solutions against the analytic solutions to the impact problem between a semi-infinite stationary workpiece and a rigid particle at the impact speeds of 25 and 12.

^{[2]}An analytical method based on Laplace transformation is used to solve the impact problem.

^{[3]}However, with recent advances, such as the discovery of new methods for persister enrichment and isolation, this is the most opportune time to apply proteomics to tackle this high-impact problem of bacterial persistence.

^{[7]}Such work could give conducive insights to contact-impact problems of the key parts or structures composed of composite materials in mechanical system.

^{[8]}The method is developed mathematically for one dimensional hydrodynamic problem, but has been used successfully for more complex applications including high-impact problems, explosive detonation in air and underwater explosions.

^{[9]}The force integration method (FIM) and the methods based on the mode transfer principle are the frequently used choices for solving the vibro-impact problem of continuum.

^{[10]}The importance of impact problems has led to extensive research work over the years.

^{[11]}For numerical simulations of impact problems or fluid–solid interactions, the ALE (Arbitrary Lagrangian–Eulerian) approach is a useful tool due to its ability to keep the computational mesh smooth and moving with the fluid.

^{[12]}Therefore, the corrosion and impact problems of reinforcements could be solved by replacing ordinary reinforcements with stainless steel reinforcements and (2) when the reinforcement ratios were large (1.

^{[13]}Past analysis and numerical simulation work related to rub-impact problems primarily focus on the complicated nonlinear vibration responses caused by the rubbing force.

^{[14]}Impact problems are an important class of problems usually accompanied by large deformations and sometime fracture of the impacting bodies.

^{[15]}TSA are common, high-impact problems in advanced cancer.
