碩士 === 中原大學 === 土木工程研究所 === 101 === In this study, the main purpose is to develop two formulations of the contact force and impulse for two concrete blocks during collision. ANSYS LS-Dyna software is used to simulate the experiments of the collision of the concrete block, and to propose these two formulations. The concrete model Mat072R3 is adopted. This model can consider the strain rate effect of the concrete. The contact detection in LS-Dyna is automatic model. This detection model can be used to simulate multi-body contact detection and arbitrary geometry. According to compare the experiments and the numerical results, they are very close. It confirms the effective and accurate of proposed two formulates of the concrete.
