Experimental investigation of the strain‐rate effects on the failure of composite materials with off‐axis tensile tests on unidirectional plies

The present study experimentally investigates the mechanical response of T700/M21 Carbon Fibre Reinforced Polymers subjected to coupled shear and transverse tension at intermediate strain rates ranging from 10−3 15 s−1. Off-axis specimens with oblique tabs are used for various tests. Moreover, specimen aspect ratio is quite low, since dynamic tests performed in this study. axial stress–strain curves successfully simulated using finite element simulations a viscoelastic model. Based on these numerical simulations, specific stress correction factors computed take effect end constraints into account such low specimens. Finally, an increase material strength rate observed.
