We study the dynamic analysis of the void growth from a defect by using the finite difference method with the hyper-elastic material. As the initial condition, the sphere with small spherical void is subjected to the hydrostatic tensile load and the surfaces are fixed. The inner void surface is set to free at the time t=0. Then the radius of the inner void surface is growing transiently. The time dependence of the inner void radius is studied with the various values of the initial stretch at the outer surface.
