| Outline of Final Research Achievements |
Computational methods for simulating Tsunami and concrete fracture are required to evaluate the safety of concrete structures for Tsunami impact. In this study, a damage model based on fracture mechanics for concrete is formulated, and the crack propagation method with the damage model is developed. The comparison between numerical and experimental results shows that the proposed method is capable of simulating fracture behavior of concrete with high accuracy. A method which is capable of effectively modeling free surface flow is applied to the computational modeling of Tsunami flow. The comparison with the experimental result available in a literature shows that the proposed method can simulate 3-D water flow with moderate accuracy and low computational costs.
