考虑摩擦三维弹塑性接触边界元法

Three dimensional elastoplastic contact boundary element method with friction

边界元法与其它数值方法相比，由于具有应力和面力计算精度高的特点，非常适合于接触问题的分析。本文建立了考虑摩擦三维弹塑性接触问题的边界元法。采用此方法对板带轧制这一典型的弹塑性接触问题进行了分析，证明本文给出的方法是有效的。

he boundary element method is superior to other numerical methods in accurate prediction of stress and traction. This superiority is significantly important to describe the elastoplastic contact problems. In this paper, the three dimensional elastoplastic contact boundary element method is presented. As a example, a plate rolling process is taken to demonstrate the validity and effectiveness of our developed boundary element simulation.
