Stress wave propagation in elastic/viscoplastic cylindrical bodies containing a spherical cavity

摘要: Stress wave propagation in elastic/viscoplastic circular cylindrical bodies bounded by a plane surface and spherical surface, containing cavity, is analyzed numerically the method of direct integration governing equations bipolar coordinates. In these cases when are partially which does not coincide with coordinate numerical procedure devised deriving stress boundary conditions on using transformation rule for contravariant tensors. By obtaining results various sizes body, effect clearly demonstrated. distributions plastic fronts body also presented.
