Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <sec> <title content-type="abstract-heading">Purpose</title> <p> – The purpose of this paper is to study of propagation of plane wave and the fundamental solution of the system of differential equations in the theory of a microstretch thermoelastic diffusion medium in phase-lag models for the case of steady oscillations in terms of elementary functions. </p> </sec> <sec> <title content-type="abstract-heading">Design/methodology/approach</title> <p> – Wave propagation technique along with the numerical methods for computation using MATLAB software has been applied to investigate the problem. </p> </sec> <sec> <title content-type="abstract-heading">Findings</title> <p> – Characteristics of waves like phase velocity and attenuation coefficient are computed numerically and depicted graphically. It is found that due to the presence of diffusion effect, these characteristics get influenced significantly. However, due to decoupling of CD-I and CD-II waves from rest of other, no effect on these characteristics can be perceived. </p> </sec> <sec> <title content-type="abstract-heading">Originality/value</title> <p> – Basic properties of the fundamental solution are established by introducing the dual-phase-lag diffusion (DPLD) and dual-phase-lag heat transfer (DPLT) models.</p> </sec> </abstract>
