In this paper, we study some qualitative and numerical properties of new equations including the coupled effects thermal elastic-plastic theory with microtemperatures. We establish necessary sufficient conditions to guarantee that model dissipates energy. The one-dimensional case, which corresponds isotropic hardening problem, is chosen in order present properties. With help semigroup linear op...

This paper proposes a multi-material topology optimization formulation for thermo-elastic structures considering coupled mechanical and uniform thermal loads. The ordered-SIMP multiple materials interpolation model is introduced, combined with examples structural volume minimization under stress constraints. p-norm function the adjusted coefficient was adopted to measure global maximum stress. ...

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....

mechanical stress and maximum superconducting current have been calculated for a superconductor subjected to uniform plastic deformation. The training effect due to strain hardening o f the material is discussed. These results are compared with an analogous case when the normal transition is caused by the thermo-magnetomechanical instability. The quenching current is shown to depend on the hist...

Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...

The thermo-elastic plate system of equations is analysed. The sufficient conditions of existence, uniqueness and continuity dependence on initial data of the Cauchy problem solutions for differentialoperational equation of mixed type (a part of the equation of hyperbolic type, and a part of parabolic type) are given in this paper. If the operational coefficients are suitably chosen, the investi...
