Numerical simulation on explosion in concrete covered with soil

The numerical simulation for explosion in concrete covered with soil is performed in this paper 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. As a consequence, the damage zone of concrete at different depth of charge (DOC) is procured. Moreover, wave propagations with attenuation in concrete and on the concrete-soil interface are obtained, respectively. The numerical results will provide reference for the design of warhead and protective structure and blasting.
