Exploratory Development of Basic Failure Behavior of Anisotropic Polymeric Material.

Abstract

Crack extension in laminated composite has been analyzed through classical laminated plate analysis. The stress vector acting on the periphery of a critical volume encap- sulating the crack tip is obtained. This stress vector is compared to the strength vector. The comparison is made through polar representation of the stress and strength vector from the crack tip. Experimental results supported the hypotheses that the coincidence of the stress and strength vector determine the crack propagation trajectory. (Author, modified-PL)
