The process of metal perturbation growth includes complex material dynamic response like great distortion, high strain rate and high pressure loading, etc. The modified Smoothed Particle Hydrodynamics (SPH) combining with dynamic constitutive behavior of metal wass used to simulate the perturbation growth with different initial amplitude of the perturbation. The influence of shear modulus and yield strength to the perturbation growth was studied. The calculated results indicate the method can also solve the metal perturbation growth problem well.
