Abstract

Present article is concerned with the propagation of plane waves in a nonlocal, microstretch thermoelastic half-space with temperature dependent properties. Five basic waves consisting of three sets of coupled longitudinal waves and two sets of coupled transverse waves travel with distinct speeds in the considered medium. The numerical values of amplitude ratios are shown graphically to explore the effects of temperature dependent properties, nonlocal and microstretch parameters. The effect of nonlocality on the phase speeds and attenuation coefficients of propagating waves have also been observed. It has also been verified that there is no dissipation of energy during reflection phenomenon.

摘要

本文章关注的是平面波在具有温度相关特性的非局部、微拉伸热弹性半空间中的传播。由三组耦合纵波和两组耦合横波组成的五个基本波在所考虑的介质中以不同的速度传播。幅度比的数值以图形方式显示，以探索与温度相关的特性、非局部和微拉伸参数的影响。还观察到非定域性对传播波的相位速度和衰减系数的影响。还验证了在反射现象期间没有能量耗散。
