Abstract

A simplified J_Ic test procedure has been proposed for determining J_Ic experimentally from a single specimen. The experimental results have shown that the crack initiation property directly influences the crack propagation behavior of the materials. Measurement of a critical J value corresponding to a small finite amount of crack growth instead of to an assumed blunting line procedure is proposed.
