✦ Synopsis

A finite element numerical model is presented which simulates vibrations in and around inclusions in viscoelastic fluids excited by a sinusoidal pressure wave or pulse generated by noisy machinery. Stress transfer processes are investigated and regions of highest energy dissipation identified. The model simulates the time evolution of stress generation in and around inclusions in the viscoelastic plastic fluid in three space dimensions. Fluid composites recommended for their power dissipative characteristics are ranked according to their ability to dissipate acoustic power in a simple composite structure.
