Abstract Present analysis is concerned with the propagation of plane waves in an initially stressed magneto-thermoelastic half-space with microtemperatures and voids. It is noticed that there exist four kinds of coupled dilatational waves in addition to shear and microtemperature waves in such type of medium. Using appropriate boundary conditions, the amplitude and energy ratios for the reflected waves have been presented in closed form when (i) a set of coupled dilatational waves is made incident and (ii) a shear wave is made incident. Amplitude ratios of various reflected waves are presented graphically to explore the effects of magnetic field, initial stress and void parameter. It is verified that there is no loss of energy at the free surface during reflection phenomena.

具有空隙和微温的初始应力磁热弹性介质中的波传播

摘要 目前的分析涉及平面波在具有微温和空隙的初始受力磁热弹性半空间中的传播。值得注意的是，在这类介质中，除了剪切波和微温波外，还存在四种耦合的膨胀波。使用适当的边界条件，当 (i) 一组耦合膨胀波入射和 (ii) 剪切波入射时，反射波的振幅和能量比以闭合形式呈现。各种反射波的振幅比以图形方式呈现，以探索磁场、初始应力和空隙参数的影响。经验证，在反射现象期间，自由表面没有能量损失。
