| Abstract: | To describe the interaction of the explosion field and the structure,a 2-D Euler-Lagrange coupling method was developed to couple a Eulerian code and a Lagrangian code.The Eulerian finite differential code called MMIC(multi-materials in cell) was used to simulate the behavior of the explosion field.And the dynamic finite element code was used to calculate the response of structures.The Euler-Lagrange coupling method was used to simulate the process of deformation and penetration of an explosion-drived fragm... |
