Thermal Stresses in Materials with Temperature-Dependent Properties

the current state of thermoelastic problems in materials with temperature dependent properties is described for analytical treatments. We discuss a perturbation method to analyze the thermelastic problems, and an new treatment for heat conduction problem in the non-homogeneous body. Thermoelastic problems in Functional Gradient Plates(FGP) are treated for a steady state and an unsteady state. Thermoelastic problems in the FGP with a crack are also considered.
