In this article, we analyzed the effect of variable thermal conductivity on reflected elastic waves. The waves are propagating through a thermoelastic medium rotating with some angular frequency. The concept of micro-temperature is also been considered, in which microelements of the medium contain a high temperature. A heat conduction phenomenon is encountered by dual phase-lag heat conduction model. P (or SV)-type wave is incident on the medium with some specific angle of incidence. After reflection from the surface incident, P-wave is converted into quasi longitudinal and quasi transverse waves and propagates back into the medium. Helmholtz’s potential function along with the harmonic wave solution is used to obtain the solution of the model. Analytically, we calculated the amplitude ratios and attenuation factor for each reflected wave against the angle of incidence. The obtained results are also represented graphically for different values of rotational frequency and variable thermal conductivity for a particular material.

波在旋转的弹性介质中的反射现象具有微温效应

在本文中，我们分析了可变导热系数对反射弹性波的影响。波通过以某个角频率旋转的热弹性介质传播。还考虑了微温度的概念，其中介质的微量元素包含高温。双相滞后热传导模型遇到热传导现象。P（或SV）型波以一定的入射角入射到介质上。从表面入射反射后，P波被转换为准纵向波和准横向波，并传播回介质中。亥姆霍兹的势函数与谐波解一起用于获得模型的解。从分析上 我们针对入射角计算了每个反射波的振幅比和衰减因子。对于特定材料的旋转频率和可变热导率的不同值，还用图形表示了获得的结果。
