A unilateral contact problem without friction in quasi-coupled thermo-elasticity and with uncertain input data is analysed. The worst scenario method is used to nd the most "dangerous" admissible input data.

Energy estimates show that linearized thermo-elasticity deenes a contraction semi-group on a Hilbert space. We show that under a geometric condition this contraction is not strict, or, more precisely, the norm of the semi group is 1 for all t 0. Convex domains always satisfy the geometric condition. 2. introduction Let R n be a bounded domain with smooth boundary ?. We consider the problem @ 2 ...

In this work, we propose an efficient matrix decomposition algorithm for the Method of Fundamental Solutions when applied to three–dimensional boundary value problems governed by elliptic systems of partial differential equations. In particular, we consider problems arising in linear elasticity in axisymmetric domains. The proposed algorithm exploits the block circulant structure of the coeffic...

This research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. Heat conduction equation in cylindrical coordinate system is solved. Thermal conductivity coefficient is graded along the radial direction. By considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

Objective: To investigate the effect of voids on propagation plane waves in a generalized thermo-elastic solid. Method: The method harmonic solution is employed to solve basic equations void solids. Findings: Under and non-voids, three sets longitudinal are derived, they not appeared any classical theory elasticity. But one transverse wave derived these results coinciding with Novelty: MATLAB p...

The analysis of rotational effect on the characteristics of plane waves propagating in a half space of generalized thermo-piezoelectric medium is presented in context of linear theory of thermo-piezoelectricity including Coriolis and centrifugal forces. The governing equations for a rotating generalized thermo-piezoelectric medium are formulated and solved for plane wave solutions to show the p...

The term “optical thermoelasticity” is used to describe how the optical properties of a material change when it heated or deformed mechanically. issues effective elastic and heat transfer symmetry are given particular focus. This study gives new nonlocal theoretical formulation for thermo-optical that can be thermomechanical waves plasma relate semiconductor materials such as silicon germanium....
