| 摘 要： | 对复合材料开口补强层合板进行压缩试验研究,分析损伤和破坏部位,然后建立补强后层合板有限元模型,分别利用非线性分析和线性分析两种方法对应力应变响应、失效强度、损伤扩展进行模拟,通过试验数据对数值结果进行考核,结果发现非线性分析较线性分析方法能更好地符合试验结果.

| Abstract: | The finite element modeling under compressive static load of repaired composite lamina is reported, and two methods: geometry non-linear method, linear method are applied to compute the stress-strain response of the repaired laminate. Then finite element models are analyzed with the ABAQUS package two-dimensional S8R shell elements. Non-linear geometry effects are taken into account in the presented model. The predicted strain distribution, damage evolution and strength of the laminate are compared with experimental results. |
