Analytical study of transient thermo-mechanical responses of dual-layer skin tissue with variable thermal material properties

Biothermomechanics involves bioheat transfer, biomechanics, burn damage and physiology. Comprehension of biothermomechanics in living tissue is very important to clinical applications. In present work, the generalized thermoelastic theory without energy dissipation is used to investigate bioheat transfer and heat-induced mechanical response in bi-layered human skin with variable thermal material properties. The governing equations of skin tissue with temperature-dependent material properties are solved by Kirchhoff and Laplace transformation. The transient thermoelastic responses and thermal damage of the skin tissue are obtained and illustrated graphically. The influences of interface and variable thermal material parameters on the responses are also discussed.
