Plane wave propagation and fundamental solution in non-local couple stress micropolar thermoelastic solid medium with voids

Abstract

In current problem, fundamental solution in an isotropic non-local couple stress micropolar thermoelastic solid with voids is investigated. We observed that there are five waves, viz. a set of three coupled longitudinal waves and a set of two coupled transverse waves propagating with different phase velocities. The impact of non-local and void parameters on the penetration depth, specific loss, attenuation coefficient and phase velocity has been studied numerically and graphically with respect to angular frequency. The fundamental solutions of the system of differential equations in case of steady oscillations have been investigated. Particular cases are established and compared with the known results.
