弹塑性接触问题是一种几何非线性和材料非线性相耦合的双非线性问题。本文针对大变形弹塑性接触以及因此而诱发的残余应力,从应用的角度出发,建立了一套耗机时少而又简便的有限元求解方法。并研制了相应的程序。
Elasto-plastic contact problem is a kind of double nonlinear problem that the geometrical nonlinearity and material nonlinearity are coupled. In this paper, aiming at the large deformation elasto-plastic contact and the induced residual stress, a set of finite element solving method with less time consuming and less time consuming is established. And developed the corresponding procedures.
