摘要
The numerical simulation for wave propagation with attenuation and damage effect in soil and concrete are performed by using the three-dimension finite element code LS-DYNA, into which the continuum damage model which can well describe the fracture of concrete is implemented. The interfacial parameters of soil and concrete vs. time and location are obtained. The laws of the damage zone of concrete with the thickness of soil are also presented. Numerical results will provide a reference for the design of warhead, the protective structure and engineering blasting.
