This paper deals with discontinuities analysis in the temperature, displacement, and stress fields of a thick plate whose lower and upper surfaces are traction-free and subjected to a given axisymmetric temperature distribution. The analysis is carried out under three thermoelastic theories. Potential functions together with Laplace and Hankel transform techniques are used to derive the solutio...

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...

Generalized thermoelastic models have been developed with the aim of eliminating the contradiction in the infinite velocity of heat propagation inherent in the classical dynamical coupled thermoelasticity theory. In these generalized models, the basic equations include thermal relaxation times and they are of hyperbolic type. Furthermore, Tzou established the dual-phase-lag heat conduction theo...

We investigate three classes of constraints in a thermoelastic body: (i) a deformationtemperature constraint, (ii) a deformation-entropy constraint, and (iii) a deformationenergy constraint. These constraints are obtained as limits of unconstrained thermoelastic materials and we show that constraints (ii) and (iii) are equivalent. By using a limiting procedure, we show that for the constraint (...
