SURFACE WAVES IN VISCO-ELASTIC INITIALLY STRESSED SOLIDS

The objective of this investigation is to study general surface waves and Rayleigh, Love and Stoneley waves as particular cases in visco-elastic solids under initial stress of hydrostatic tension or compression. Firstly, the general theory of surface waves in visco-elastic solids under initial stress has been formulated.. The visco-elasticity of the solid medium involving time rate of stress and strain is considered to be of first order, The general n-th order visco-elasticity of similar type is very cumbersome to handle. The investigated problems and the wave-velocity equations are in fair agreement with the corresponding results of the classical problems in absence of viscosity and initial stress.
