回転とひずみ自由度を有する三角形要素を用いた剛塑性有限要素法の基礎的検討

抄録

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.
