We present an application of node-based uniform strain element to mixed rigid plastic finite element analysis. Using triangular elements in rigid plastic finite element analysis often causes locking problem. In order to avoid the locking problem, we employ the node-based uniform strain element. We solve three problems to show the validity of the proposed method. The results show the effectiveness of the proposed method.
