Abstract

This article is intended to observe the reflection and transmission phenomena of three-dimensional plane waves at the interfaces of two distinct anisotropic triclinic media under the context of the three-phase-lag model and Green-Naghdi theory. Distinct interfaces, viz. normal stiffness, transverse stiffness, thermal contact conductance, welded contact and slip boundaries have been considered to examine the impact of boundaries on the reflection and transmission phenomena of the thermoelastic waves. Mathematical expressions for the reflection and transmission coefficients of the waves have been acquired in the context of generalized thermoelasticity. Energy ratios for each of the reflected and transmitted waves have been derived to establish the energy conservation law at each of the incident angles. The findings of this study are elaborated in the form of graphical means.

摘要

本文旨在在三相滞后模型和 Green-Naghdi 理论的背景下，观察三维平面波在两种不同的各向异性三斜介质界面处的反射和透射现象。不同的接口，即。法向刚度、横向刚度、热接触传导、焊接接触和滑移边界已被考虑用于检查边界对热弹性波的反射和传输现象的影响。波的反射系数和透射系数的数学表达式是在广义热弹性的背景下获得的。已经推导出每个反射波和透射波的能量比，以建立每个入射角的能量守恒定律。
