Abstract : The growth and deformation of a spheroidal void in an infinite viscous matrix is addressed. In the case of a linearly viscous newtonian matrix MATH, an exact solution is obtained. On the basis of this solution the case of a power law viscoplastic matrix MATH is dealt with by a variational approach. Finally, the Galerkine method is used to take into account inertia effects. This work shows the anisotropy of damage and the stabilizing effect of the remote strain rate MATH for a material exhibiting the linear flow rule MATH as well as the stabilizing effect of the inertia forces.
