ASYMPTOTIC WAVE-PROPAGATION IN A NON-NEWTONIAN COMPRESSIBLE FLUID WITH SMALL DISSIPATION

The spherical motion of a non-Newtonian compressible fluid is consider ed and a reductive perturbation method is used to study the point-expl osion problem. The material response functions involved in the model u nder consideration an assumed to be of polynomial form and the resulti ng Burgers-like equation which governs the far-held approximation is i nvestigated. A qualitative analysis of this equation is made via a num erical integration.
