Wave propagation in nonlocal couple stress thermoelastic solid

This work is concerned with the propagation of plane wave in an infinite isotropic nonlocal couple stress thermoelastic solid. Two problems have been evaluated by making incidence of (i) a longitudinal displacement wave and (ii) a set of coupled transverse waves. All these waves are dispersive in nature. Reflection phenomenon of an incident coupled longitudinal wave from stress free boundary surface of a nonlocal thermoelastic solid has also been studied. The dispersion curves of various waves of Magnesium crystal are calculated numerically and shown graphically. The e ffect of nonlocality has also been observed and shown graphically.
