摘要:An experimental study and numerical calculation are conducted to investigate the crack propagation in a 2D woven composite. Crack propagation tests of single-layer composite plate specimens permit this process to be directly followed. Analysis of their fracture surfaces reveals crack propagation paths, fracture mode, and damage mechanisms. The load-deflection curve represents the crack propagation as a three-stage process. The stress intensity near the crack tip is evaluated with the critical stress intensity factor numerically calculated. The results demonstrate a good agreement between the calculations and experiment.
