| 摘 要： | 荷载作用下复合材料构件应力分布状态的分析是工程实践中的一个重要环节。构件中的应力集中现象将使其产生疲劳裂纹，也能使脆性材料制成的零件发生静载断裂。而对应力集中区域的有限元计算分析是一种数值模拟方法，有一定局限性，但其有效性可以通过相应的光弹性实验加以验证。

| Abstract: | To analyze the stress distribution of composite material under load is an important step in engineering practice. And the stress concentrated phenomena will bring fatigue flaw and rupture to the engineering component. The FEM method is a kind of numerical simulation method. This method still has certain limitation, but its validity can be verified through the corresponding photo - elasticity experiment. |
