摘要
针对复合材料厚板连接件,建立三维累积损伤有限元模型预测复合材料厚板连接件的挤压性能。对复合材料层板中的纤维失效、基体失效和分层等损伤类型进行分析模拟,预测厚板连接件的破坏模式及损伤扩展过程,并分析尺寸参数与复材厚层合板连接强度的关系。
A three-dimensional thick composite laminates under te progressive damage model was set up for predicting the bearing performance of nsile loading. Analyzing and simulating the fibre damage, matrix damage and de- lamination. The 3D model has the capability of assessing the ultimate bearing strength of joints and simulating the whole process of damage initiation, propagation and catastrophic failure of the structure. The finite element method could also be used to predict the relationship between structure design parameters and load carrying capabilities.
