| Abstract: | The finite element program LS-DYNA3D was used to numerically simulate the dynamic response of damage effect for explosion in building.The result obtained by numerical simulation and that obtained by empirical formula calculation were compared and it is found that the both are consistent.The feasibility of the built finite element is proved,and it can be referred to warhead design and target protection design. |
