本文从数学基础、力学基础和物理模型的处理技术三方面系统全面地阐述了刚塑性有限元数值模拟过程中产生误差的主要原因，提出了有效的改进方法；并通过多种模拟实例加以说明。
In this paper, the main causes of errors in the rigid-plastic finite element numerical simulation process are systematically and comprehensively described from the aspects of maths foundation, mechanics basis and physical model processing. An effective improvement method is put forward and illustrated by various simulation examples.
