摘要

Crack extension in laminated composite has been analyzed by stress analysis of the crack through classical laminated plate analysis. Through such stress analysis, the stress vector acting on the periphery of a critical volume encapsulating the crack tip is obtained. This stress vector is compared to the strength vector which is independently determined by the tensor polynominal failure criterion. The comparison is made through polar representation of the stress and strength vector from the crack tip. Experimental results on a variety of lamination geometry and crack orientations supported the hypotheses that the coincidence of the stress and strength vector determine the crack propagation trajectory.
