SPHERICAL WAVES IN INELASTIC MATERIALS
Abstract
The effects of constitutive properties on spherical wave propagation are investigated through finite element calculations of an infinite medium (Cedar City Tonalite) loaded internally by a sphere of chemical explosive. Detonation of the explosive is represented by applying a pressure to the cavity surface which varies with time in a manner similar to that measured experimentally by Physics International Company. Results are presented as stress/time histories and stress strain relations at various cavity radii and as rates of attenuation of the peak radial stress. The results illustrate the effect of varying the bulk modulus, yield criterion and plastic flow rule.
