Study of the rigid plastic finite element method using triangular element with drilling and strain degrees of freedoms

Abstract

The rigid plastic finite element method is widely applied in quadrilateral finite element, and it is necessary conducted re-meshing for changing material shape by processing stage. On the other hand, it is well known that a triangular element division has highly robustness in comparison to the quadrilateral element division. In this paper, rigid plastic finite element method using triangular element with drilling and strain degrees of freedoms was investigated by analyzing fundamental numerical examples.
