| Abstract: | 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. |
