The Thermodynamics of linear irreversible processes is presented from a unified viewpoint. This provides a new and synthetic approach to the linear mechanics of deformation of solids, which includes as particular cases the classical theory of Elasticity, Thermoelasticity and Viscoelasticity. The first two sections constitute an introduction to the general concepts and principles of linear Therm...

The problem of partial exact boundary controllability and exponential stability for the higher-dimensional linear system of thermoelasticity is considered. By introducing a velocity feedback on part of the boundary of the thermoelastic body, which is clamped along the rest of its boundary, to increase the loss of energy, we prove that the energy in the system of thermoelasticity decays to zero ...

The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...

By laminating piezoelectric and flexible materials, we can increase their performance. Therefore, the electrical mechanical properties of layered materials subjected to electromechanical loads heat sources must be analyzed theoretically mechanically. Since problem infinite wave propagation cannot addressed using classical thermoelasticity, extended thermoelasticity models have been derived. The...

In this paper, the basic constitutive equations and equations of motion are derived to describe the behavior of thermoelastic porous piezoelectric medium by using Biot’s theory and the theory of generalized thermoelasticity with on relaxation time (Lord-Shulman). The electrical enthalpy density function is derived in the general coordinates. Also, clear definitions for the poroelastic modulus, ...

It is of practical significance to study the multi-physical processes solid state nuclear systems for device design, safety analysis, and operation guidance. This system generally includes three processes: neutronics, heat transfer, thermoelasticity. In order analyze field behavior system, it necessary laws neutron flux, temperature, stress, other physical fields in system. Aiming at this scien...
