A thermo-visco-plastic constitutive relation for the metal, which can cover plastic hardening (softening) behaviors, thermo-softening behaviors and damage-softening behaviors, is adopted in the numerical computation for analyzing the metal spallation induced by laser. Computations are carried out in one-dimensional and two-dimensional cases, respectively. Attenuation of shock wave pressure is calculated, as well. The calculated spallation thickness is in good agreement with the experimental observations.
