 note = {A triangular plane element with 12 degrees of freedom based on hybrid stress model is presented. Since the element has a node at midpoint of the each boundary side. The analysis is useful for treating non-linear Problems including crack and slip. For numerical examples, the element is applied for elasto-plastic analysis of the punch problem and the V-notch specimen under tensile load. The results of numerical examples are in good agreement with the ones of Finite Element Model and Rigid Body Spring Model., 紀要論文},
