## What is/are Open Hole Tensile?

Open Hole Tensile - The open-hole tensile behavior and progressive damage of GLARE laminate are studied experimentally and numerically.^{[1]}The open-hole tensile strength is also improved considerably (almost 30%) when the holes are reinforced with Ti inserts.

^{[2]}Therefore, three mechanical tests were performed: tensile tests, in-plane shear and open-hole tensile tests.

^{[3]}Moreover, an open-hole tensile test was performed to evaluate breakage tendency based on GFRP stacking conditions.

^{[4]}These tests showed that there is no critical influence of the drill-hole quality on the open-hole tensile and flexure strength of the applied CFRTP.

^{[5]}Based on the developed macro-meso coupling model of N-3DWC, the open-hole tensile strength and failure mechanisms were predicted and analyzed, and the model was validated with the experimental results.

^{[6]}A progressive damage model based on the Hashin-type criteria and zero-thickness cohesive zone method was developed by VUMAT subroutine, which was validated by both open-hole tensile test and three-point bending test.

^{[7]}In such cases, a numerical edge treatment is proposed for more accurate representation of open-hole tensile strength in large structures where holes are positioned away from free edges.

^{[8]}The model’s performance is first analyzed from a numerical point of view and then demonstrated for tensile tests ( 0 ° , 45 ° and 90 ° ), open-hole tensile tests ( 0 ° ) and three-point bending ( 0 ° and 90 ° ) tests of short fibre-reinforced polypropylene with 15 wt.

^{[9]}On another hand, the effect of stress concentration was verified with testing the specimens through open hole tensile (OHT).

^{[10]}Matrix grading through local deposition of additive-enhanced matrices and fibre steering by varying fibrous architecture are examined independently and in combination on a glass-fibre triaxial braided composite subjected to open hole tensile test.

^{[11]}An alternative method could be the Open Hole Tensile Test, which was developed for fiber composites testing.

^{[12]}After identifying the optimum parameters, open hole tensile test was performed on the notched specimens.
