Original Abstract

Theoretical and experimental work are made for bridged cracks in chevron-notched three point bend specimens made of glass matrix composite reinforced by long SiC fibres. The fracture toughness (KIC) values are determined using the chevron-notch technique and com- pared with the theoretical predictions based on micromechanical analysis exploiting weight functions. The weight functions for ortho- tropic material are obtained numerically by means of detailed FEM analysis using the ANSYS package and they are further used together with appropriate bridging models for the theoretical prediction of the R-curve behaviours typical of the investigated composites.
