In this paper, we deal with the numerical approximation of some porous-thermoelastic problems. Since inertial effects are assumed to be negligible, resulting motion equations quasistatic. Then, by using finite element method and implicit Euler scheme, a fully discrete is introduced. We prove stability property main error estimates result, from which conclude linear convergence under appropriate...

Abstract The present research focuses on two-dimensional deformation in a functionally graded thermoelastic micro-elongated medium. It is supposed that the non-homogeneous properties (thermal and mechanical) of FGM are x-direction. normal mode technique used to acquire analytic expression for displacement components, stress, micro-elongation temperature. cause effect relationship non-homogeneit...

Abstract-In order to adequately reproduce the thermo-mechanical behaviour of metals under finite volume reduction and large temperature increase, it is necessary to use the second order thermoelastic analysis, i.e. to use the free energy function expanded up to the third degree in strain and tcmpcrature. Determination of the corresponding material constants is given and the resulting expression...

We consider the stability properties for thermoelastic Bresse system which describes the motion of a linear planar shearable thermoelastic beam. The system consists of three wave equations and two heat equations coupled in certain pattern. The two wave equations about the longitudinal displacement and shear angle displacement are effectively damped by the dissipation from the two heat equations...

In this work, an analytical solution for thermoelastic waves in a metal induced by an ultrafast laser pulse was formulated in the form of a Fourier series. The two-step heat transfer model was applied to account for the thermal nonequilibrium between electrons and the lattice during ultrafast pulsed laser heating. The coupling between the strain rate and the temperature ®eld was also considered...

l13Cd NMR measurements in two Ag-Cd samples cycled between room temperature and temperatures below M, are presented. The growth curve of the martensite on cooling presents a discontinuity in the cycling temperature region. It is shown that the method of analysis of the NMR data recently developed by us [Phys.Rev.B 46, 10563 (1992)], allows to detect subtle memory effects and the absolute determ...
