Abstract

In this study, a triangular plane element with 12 degrees of freedom based on hybrid stress element is applied to fracture analysis of concrete. This element is useful for treating non-linear problem including discrete crack because it has a node at midpoint of the each boundary side. In numerical analysis by which the tension softening is considered, the unstable phenomenon such as snap-back is often appeared. Therefore, authors developed the algorithm which can apply the analysis for an unstable phenomenon. To clarify the validity of this method, the fracture of the CT specimen and notched concrete beam were simulated by proposed method. The analytical results are in good agreement with the experimental ones.
