摘要

摘要: 研究具有两个驰豫时间的、两个不同弹性和热性质的、广义传热立方晶体固体半空间的有缺陷结合面上，热弹性平面波的反射和折射问题．具有两个驰豫时间的广义热弹性理论，是1972年由Green和Lindsay提出并应用于问题的研究．对有缺陷边界，给出了反射系数和折射系数（即反射波和折射波振幅与入射波振幅之比）的表达式，并推演了法向刚性边界、横向刚性边界、接触传热边界、滑动边界和结合面边界时的表达式．给出了在不同边界条件及出射角时，不同的反射波和折射波的振幅比，在不同的入射波时的变化图．发现反射波和折射波振幅比受到介质刚性和热性质的影响．

Abstract: A problem concerning with the reflection and refraction of thermoelastic plane waves at an imperfect interface between two generalized thermally conducting cubic crystal solid half-spaces of different elastic and thermal properties with two relaxation times has been investigated.The generalized thermoelastic theory with two relaxation times developed by Green and Lindsay has been used to study the problem in 1972.The expressions for the reflection and refraction coefficients which are the ratios of the amplitudes of reflected and refracted waves to the amplitude of incident waves were obtained for an imperfect boundary and deduced for normal stiffness,transverse stiffness,thermal contact conductance,slip and welded boundaries.Amplitude ratios of different reflected and refracted waves for different boundaries with angle of emergence were compared graphically for different incident waves.It is observed that the amplitude ratios of reflected and refracted waves are affected by the stiffness and thermal properties of the media.
