Prediction of Mixed Mode Crack Propagation Direction in Carbon Fiber Reinforced Plastic Plate
A newly developed Z-fracture criterion is introduced in this paper by introducing the new concepts of in-plane dilatational strain energy density factor, in-plane average strain and reciprocal function. The Z-fracture criterion is applied to predict the mixed mode crack propagating direction in carbon fiber reinforced plastic (CRP) plate. The test results show that the Z-fracture criterion can be successfully used to predict the mixed mode crack propagation direction in CRP plate.
