利用应力强度因子折减系数的概念,来考虑纤维增强等的影响,从而可把各向同性体复合型脆性断裂的周向应变因子准则,推广应用于单向复合材料断裂分析。计算结果同E型玻璃钢Scotchply 1002的试验数据符合得很好。
By using the concept of reduction factor of stress intensity factor, the influence of fiber reinforcement and so on can be considered. Therefore, the circumferential strain factor criterion for isotropic bulk brittle fracture can be extended to the fracture analysis of unidirectional composite material. The calculated results are in good agreement with the experimental data for E-type FRP Scotchply 1002.
