Abstract
Numerical simulation of spallation in a steel plate due to explosive loading is studied by 2D finite element method. A generalized elastic-plastic constitutive relation is considered to describe the isotropic strain hardening, strain softening and kinematic hardening in the same relation. The damage-accumulated criterion and a semi-coupled damage constitutive model are taken as a critical condition of spallation respectively. Numerical results show that the thickness of spalled layer of 2D simulation is thinner than that of 1D simulation but the residual velocity of the flying layers of 2D is much lower than that of 1D. It is concluded that the results of 2D simulation are more reasonable and acceptable as compared with the engineering experiments.
