MAGNETO-THERMOELASTIC RAYLEIGH WAVES IN A PRESTRESSED SOLID HALF-SPACE UNDER HEAT SOURCE USING GREEN AND LINDSAY'S MODEL

摘要

An in-depth study has been carried out for the propagation of the Rayleigh waves in thermo-magneto-elastic halfspace under the effect of initial stress and heat source. Using GL theory of thermoelasticity, the frequency equation is derived for the said waves under the effect of various technical constants. The wave analysis further indicates that the initial stress, magnetic pressure number, thermoelastic coupling parameter, wave number, and heat source for cadmium material affect the Rayleigh wave velocity remarkably. The obtained results in presence of material parameters are further discussed graphically. The results can be useful to understand the working of highly sensitive thermal stress magnetic sensors.
