Abstract

Abstract

Two-dimensional finite element analysis of the double-cantilever beam specimen was performed using 8-node isoparametric,quadrilateral elements to evaluate compliance and strain-energy-release rate G_I. The G_I values were computed using J-integral method. The effects of the carck length,the thickness of specimen and the modular in thickness direction on the evaluation of G_I according to simple-beam-theory were investigated.
