Department of Defence, Materials Research Laboratory, DSTO, P.O. Box 50, 3032, Ascot Vale, Victoria, Australia aut Modelling of nonlinear dilatation response of fluids containing columns plastic and shear relaxation considered [Elektronische Daten] [B. Wendlandt] Summary: The non-linear wave equation governing the propagation and scatter of dilatation waves in discontinuous media is presented and its Eulerian numerical analogue is used to study scatter of acoustic dilatation waves by colums and ducts in elastic and visco-elastic fluids. Plastic and visco-elastic relaxation mechanisms are considered. The spectral form of the wave equation is developed and used to discuss dispersion. Selected applications of the numerical analogue to simulation of scatter, propagation and echo attenuation presented.
