摘要
基于有限元方法,利用有限元分析软件MSC.Patran/Nastran,建立复合材料层合板阶梯式挖补修理三维有限元模型,采用相对刚度分析方法,得出不同挖补阶数和胶层厚度对复合材料层合板阶梯式挖补修理结构刚度的影响规律。
Based on the finite element method and with the finite element analysis software MSC. Patran/Nastran, this paper establishes the three - dimensional finite element model of stepwise repairs of composite laminated plates, uses the relative stiffness analysis method, and comes to the influencing rules of various parameters such as repairing steps and adhesive thickness to structural stiffness of stepwise repairs of composite laminated plates.
