摘要
本文应用摄动有限元法,分析增量理论的弹塑性问题,采用关联性流通法则及德鲁克一普拉格(Drucker-Prager)屈服函数建立弹塑性本构关系,导出了摄功有限元基本方程,通过实例的计算取得了良好的效果。
In this paper, the perturbation and finite element method are used to analyse the elastic-plastic problem of incremental theory and the associated flow rule and Drucker-Prager yield function are used to establish the constitutive relation. Then the basic equation of perturbation and finite element method is derived. Through the calculation of a practical example, this method shows good result.
