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 introduce the coupled theory, Lord-Shulman theory with one relaxation time and Green-Lindsay theory with two relaxation times to study the influence of rotation on generalized micropolar thermoelasticity subject to thermal loading due to laser pulse. The bounding plane surface is heated by a non-Gaussian laser beam with pulse duration of 8 ps. </p> </sec> <sec> <title content-type="abstract-heading">Design/methodology/approach</title> <p> – The problem has been solved numerically by using the normal mode analysis. </p> </sec> <sec> <title content-type="abstract-heading">Findings</title> <p> – The thermal shock problem is studied to obtain the exact expressions for the displacement components, force stresses, temperature, couple stresses and micro-rotation. The distributions of the considered variables are illustrated graphically. Comparisons are made with the results predicted by three theories in the presence and absence of laser pulse and for different values of time. </p> </sec> <sec> <title content-type="abstract-heading">Originality/value</title> <p> – Generalized micropolar thermoelastic solid.</p> </sec> </abstract>
