We introduce the coupling of three-dimensional transient electro-thermal interconnect simulations with intrinsic thermo-mechanical stress solutions. In order to study the development of local thermal stresses we use a finite element simulator for the investigation of complex layered interconnect structures at different operating conditions. The obtained local stress, temperature distribution, t...

In this article, the influence of important parameters on size-dependent thermoelastic behavior functionally graded magneto-electro-thermo-elastic microcylinders (FGMEE) is studied by means modified stress couple theory and under combined mechanical-thermal-magnetic loads. The equations motion were derived considering linear shells first-order nonlocal shear deformation shells. following, resul...

in this paper, an ultra low carbon high strength low alloy grade steel was subjected to a two-step forging processand this was followed by different post cooling methods. the highest strength was obtained at a faster coolingrate due to the highly dislocated acicular ferrite structure with the fine precipitation of microalloying carbides andcarbonitrides. at a slow cooling rate, the strength fel...

The purpose of this research is to correctly model steady-state heat transfer in and around rectangular bus bars installed horizontally an indoor environment estimate the corresponding ampacities, considering effects horizontal transverse vibrations caused by electromagnetic forces. This thermo-electro-magneto-mechanical problem solved analytically using correlations determined experimentally o...

In this article, axisymmetric buckling behavior of piezoelectric fiber reinforced polymeric composite (PFRPC) annular plate subjected to electro-thermo-mechanical field is presented utilizing principle of minimum potential energy. Boron-nitride nanotubes (BNNTs) are used as fibers. Full coupling between electrical, mechanical and thermal fields are considered according to a representative volum...

In this study, free vibration of a foam-core orthotropic smart composite cylindrical shell (SCCS) filled with a non-viscous compressible fluid, subjected to combined electro-thermo-mechanical loads is investigated.  Piezoelectric polymeric cylindrical shell, is made from polyvinylidene fluoride (PVDF) and reinforced by armchair double walled boron nitride nanotubes (DWBNNTs). Characteristics of...

In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...
