Stress Wave Propagation in Elastic/Viscoplastic Media Containing a Spherical Cavity

摘要: Stress wave propagation in an elastic/viscoplastic sphere containing eccentric spherical cavity is analyzed numerically by the method of direct integration governing equations bipolar coordinates, when axisymmetric dynamic load and a non-axisymmetric dynamic, frictional are applied simultaneously onto small part sphere. On basis numerical examples obtained, stress distributions plastic fronts demonstrated for successive times. ground also using constitutive normally consolidated clay. The bulging surface behavior contour illustrated.
