摘　　要：采用非线性有限元分析软件ABAQUS对型材压损破坏形式以及承载能力进行了分析,在分析中考虑了材料非线性、几何非线性。有限元分析结果与试验结果对比表明,仿真分析结果可以准确地模拟型材压损破坏形式及承载能力,该仿真分析方法可以用于飞机设计工作。The nonlinear finite element analysis software ABAQUS is used to simulate the crippling failure of shapes and their loading capabilities. Material nonlinearity and geometry nonlinearity are taken into account during analysis. Comparison between simulation results and test results shows that the simulation analysis can be used to simulate failure modes and loading capabilities accurately, and the simulation method can be used in the airplane structure design.
