复合材料非平面连接接头强度预测

基于渐进损伤分析方法,对一种复合材料非平面连接接头承受轴向拉伸载荷作用下的失效强度进行了研究,建立了三维渐进损伤有限元模型预测连接结构的失效行为,预测的失效载荷和载荷-位移曲线与试验结果的对比一致,验证了分析的有效性。

Tensile Strength Prediction of Out-of-Plane Composite Joints

Based on the progressive damage analysis method,the failure of an out-of-plane composite joint under

axial tensile loading is investigated. A progressive damage model consisting of a three dimensional FEM model is established

to predict the failure behavior of the joint. The predicted failure load and load-displacement curve are validated

by the experimental results.
