| 摘 要： | 针对复合材料裙级间螺栓-柱销连接结构试件,建立了三维有限元逐渐损伤模型。该模型可模拟试件损伤起始、发展及最终破坏的整个过程,并能较好预测试件破坏的模式和强度。该模型包括应力分析、失效判定准则和材料性能退化3个步骤,采用该模型对试件进行了损伤扩展分析和强度预测,计算结果与实验结果较吻合。 |
| 关 键 词： | 连接结构 逐渐损伤破坏 破坏准则 强度预测 有限元分析 |

| Abstract: | Aiming at bolt-plug connecting pieces of composite skirts,a 3D finite element gradual damaging model was derived.The model can be used for simulating the overall process of sample damaging,such as initiation,development and final failure,and perfectly predicting failure mode and strength of sample.The model includes three stages,such as stress analysis,failure criteria,material property degradation.The model was used for damaging analysis and strength prediction,and the calculated results agreed well with the experimental results. |
| Keywords: | joint structure gradual damaging failure failure criteria strength prediction finite element analysis |
