摘要
本文对应力梯度较小的部分采用有限元法,对应力梯度大和带开孔且形状复杂的部分采用边界元法,建立了由薄板组成的三维结构耦合方程,分析了弹性和弹塑性应力状态。
The coupling equations for 3-D structure composed by thin plates are established by adopting the FEM for the domain with slight stress gradient and the BEM for the domain with large stress gradient owing to the complex form and existence of holes. The elastic analysis and elasto-plastic analysis are also given.
