Electro-magnetic-thermal-microstretch elastic mathematical-physical model of semiconductor medium is investigated. The governing equations are studied in the context photo-thermoelasticity theory during photothermal transport process. exposed to an external magnetic field and a beam laser. coupled between electromagnetic field, thermal, plasma waves when inertia-microstretch properties material...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

It is seen how to write the standard form of the four partial differential equations in four unknowns of anisotropic thermoelasticity as a single equation in one variable, in terms of isothermal and isentropic wave operators. This equation, of diffusive type, is of the eighth order in the space derivatives and seventh order in the time derivatives and so is parabolic in character. After having ...
