Coupled thermoelasticity of FG-GPLRC multi-curved composite panel under thermal shock loading

Abstract This study is dedicated to explore the transient coupled thermoelasticity solution of the FG-GPLRC multi-curved composite panel subjected to thermal shock for the first time. Time dependent equations of motion within the context of theory of elasticity are formulated and analytically solved by means of Navier approach. The temperature gradient is acquaried by employing the energy balance equation for the composite cylindrical panel subjected to thermal shock at its outer surface and thermally isolated at its inner surface. The time history of deflections, stresses and temperature are acquired by applying modified format of Dubner’s and Abate’s technique to inverse the Laplace transform . The effective thermoelastic properties of the composite are calculated according to correlations presented by modified form of Halpin-Tsai micromechanics . The numerical results of this study are compared with those recorded in the associated high-quality sources to verify their accuracy. The thorough parametric exploration is executed to analyze the role of various items like mid-radius to thickness ratio , distribution patterns and weight fraction of GPL in the transient coupled thermoelasticity response of FG-GPLRC multi-curved composite panel.
