Design and Analysis of Orthotropic Composite Materials Through a Mixed Mode Cohesive Crack Simulation
A Mixed Mode crack analysis is applied to simulate the failure mechanism of the Iosipescu shear test for a fibre-reinforced composite. The stability of the curvilinear crack trajectory appears to be sensitive to the ratio between the principal strengths. For a strongly orthotropic material, the zig-zag trajectory results to be alternately parallel to the fibres or directed towards the loading point.
