最小ポテンシャルエネルギーの原理に基礎をおく有限要素法の節点における応力の一評価法

In this paper a nodal stress evaluation method in a model based on approximate displacement fields is presented. This method is based on weighted residiual and finite-element approximation, so it is easy to evaluate the stresses at the nodal point. In order to demonstrate the efficiency of the method, results of several simple examples inrolving the computation of stresses at the nodal points are shown.
