对二维编织复合材料的裂纹扩展进行了实验研究和数值计算。单层复合材料板试件的裂纹扩展试验允许直接遵循这一过程。对其断口表面的分析揭示了裂纹扩展路径、断裂模式和损伤机理。荷载-挠曲曲线表示裂纹扩展为一个三阶段过程。利用数值计算的临界应力强度因子对裂纹尖端附近的应力强度进行了评估。计算结果与实验结果吻合较好。
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.
