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...

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 (...

The elastic properties of the human red blood cell membrane have been measured as functions of temperature. The area compressibility modulus and the elastic shear modulus, which together characterize the surface elastic behavior of the membrane, have been measured over the temperature range of 2-50 degrees C with micropipette aspiration of flaccid and osmotically swollen red cells. In addition,...

The article is concerned with a new nonlocal model based on Eringen’s nonlocal elasticity and generalized thermoelasticity. A study is made of the magneto-thermoelastic waves in an isotropic conducting thermoelastic finite rod subjected to moving heat sources permeated by a primary uniform magnetic field and rotating with a uniform angular velocity. The Laplace transform technique with respect ...

We construct the analytic solution of a three-dimensional problem thermoelasticity for transversely isotropic space with internal stationary heat sources. By method direct integration, is reduced to system governing equations components stress tensor, which solved by using double integral Fourier transform.
