Abstract : A finite difference method for predicting the effect of shock waves on a circular cylindrical cavity in elastic-plastic media was studied. A two-dimensional Lagrangian code was found quite satisfactory. Attenuation of the shock waves through the cavity and the deformation of the cavity wall were discussed. (Author)
