In the paper, a local stationary model of thermoelastic state porous material is constructed. The based on uncoupled boundary value problems for equations heat conduction and thermoelasticity space with two spherical cavities. temperature field determined by constant surfaces cavities, which are considered free forces. problem was solved generalized Fourier method (GFM), paper presents its furt...

We have studied the high-pressure behavior of periclase ~MgO! using density functional simulations within the generalized gradient approximation. The static and thermal (P-V-T) equation of state, B1-B2 transition pressure, elastic constants, Grüneisen parameter, and the intrinsic anharmonic parameters were calculated from static and ab initio molecular dynamics simulations. The simulations were...

An analysis of the propogation of thermoelastic waves in a homogeneous, anisotropic, thermally conducting plate has been presented in the context of the generalized Lord-Shulman theory of thermoelasticity. Three different methods are used in this analysis: two of them are exact and the third is a semianalytic finite element method (SAFE). In our exact analysis, two different approaches are used...

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 ...
