Study the effects of temperature and strain rates on transient thermomechanical responses on multilayer skin tissue

Abstract

The present study is focused on understanding the effects of strain and temperature rates on heat transport mechanisms and the related thermo-mechanical interaction with skin tissue, which are essential for the effective application of thermal therapeutic techniques. The goal of this article is to develop a mathematical framework to investigate the thermo-mechanical phenomena occurring on triple-layered skin tissue using the Modified Green-Lindsay model (MGL) by taking into consideration of two thermal relaxation parameters. This model takes into consideration the effect of strain and temperature rate factors in thermoelastic behaviour which was neglected in several other thermoelastic models. The problem is formulated in a unified way to derive the governing equations and constitutive relations under the present model and also the thermoelasticity with two phase-lag parameters. A comprehensive assessment of solution is discussed for MGL model and compared the results with the corresponding results predicted by dual phase lag generalized thermoelastic model that involves two phase-lags. The effect of strain rate term in heat transport on skin tissue are especially highlighted.
