Abstract
The aim of this Thesis, estimate the effect of the electric field, magnetic field, rotation, initial stress, diffusion, void, fibre reinforced ,microstretch and micropolar under varying models of thermoelasticity. This Thesis has a lot of applications in many engineering fields such as modern aeronautics, astronautics, earthquake engineering, soil dynamics, mining engineering, nuclear reactor design, high energy particle accelerators, geothermal engineering, geophysics, plasma physics, optics, atomic physics, industrial engineering, thermal power plants ,technology, submarine structures, pressure vessel, aerospace, chemical pipes and metallurgy,…, etc. This Thesis consists of seven chapters, we present them as follows: Chapter one: we introduced the literature survey in the works made in this branch and basic equations concern the basic concepts and their relations. Also, this chapter can be considered as a background for studying of elastic media under theories of thermoelasticity which we used in this Thesis. Chapter two: we study the effects of the rotation, magnetic field and gravity in a thermoelastic half-space containing heat source on the boundary of the half space . The medium assumed under consideration is traction free, homogeneous, isotropic, as well as without energy dissipation. The normal mode analysis and eigenvalue approach technique are used to solve the resulting non dimensional coupled equations. The comparisons for the physical quantities are established numerically and xiv.
