This work is devoted to a study of the induced temperature and stress fields in an elastic half space in context of clas-sical coupled thermoelasticity and generalized thermoelasticity in a unified system of equations. The half space is con-sidered to be made of an isotropic homogeneous thermoelastic material. The bounding plane surface is heated by a non-Gaussian laser beam with pulse ...

Recent advances in generalized thermoelasticity theory and ...

The thermoelasticity theory is a combination of elasticity and heat conduction theories. It is related to the impact of heat on the deformation of an elastic medium and the inverse impact of the deformation on the thermal condition of the considered medium. Thermal stress is produced when the time rate of variation of a heat source in a medium ...

[2109.15151] Weak-strong uniqueness for measure-valued ...

This article studies the equations of adiabatic thermoelasticity endowed with an internal energy satisfying an appropriate quasiconvexity assumption which is associated to the symmetrisability condition for the system. A Gårding-type inequality for these quasiconvex functions is proved and used to establish a weak-strong uniqueness result for a class of dissipative measure-valued solutions.

Thermoelasticity - EOLSS

The theory of thermoelasticity is concerned with the interaction between thermal field and the elastic bodies. The study of thermoelasticity was begun by Duhamel (1837) and Neumann (1885) who postulated the equations of the linear thermoelasticity for isotropic bodies. These equations have been justified by Biot (1956) on the basis of
