Dielectric elastomers are a class of solid polymeric materials that sufficiently soft to deform under the application an electric field due interaction quasi-static charges. Their potential undergo large deformations renders them promising candidates for design energy harvesters, sensors and actuators. For their however, influence additional thermal effects should be taken into account as base ...

In this paper the basic mathematical structure of a thermo-poro-mechanical model for faults under rapid shear is discussed. The analysis is 1D in space and concerns the infinitely extended fault. The gauge material is considered as a two-phase material consisting of a thermo-elastic fluid and of a thermoporo-elasto-viscoplastic skeleton. The governing equations are derived from first principles...

Nanowires (NWs) exhibit thermo-mechanical properties that are distinct from their bulk properties, and their understanding is critical for the reliability, manufacturability, and optimization of a wide range of devices consisting of NWs. Here, molecular-dynamics simulation reveals a rich size-temperature “phase diagram” for the mechanical response of a zinc-oxide NW under tension. For smaller d...

in this paper, a thermoelasticity solution for steady state response of thick cylinders which are subjected to pressure and external heat flux in inner surface is presented. displacement field obeys the kinematics of the first order shear deformation theory (fsdt). it is assumed that the temperature varies both along the length and the thickness. the variation of the temperature occurs linearly...

In this paper, new numerical modeling of material flow in the thermo-mechanical friction stir welding process is presented. In this numerical model, the discretization in space is derived by the meshfree Galerkin method using a Lagrangian meshfree convex approximation. The discrete thermal and mechanical equations are weakly coupled as the time advances using a forward difference scheme. A mort...

In recent years, increasing automotive safety by improving crashworthiness has been a focal point in the industry, employing high-strength steel such as press hardenable (PHS). addition to improved strength of individual parts body vehicle, resistance-spot-welded joints these is highly important obtain safe structure. general, dimensions weld nuggets are regarded one criteria for quality spot-w...

An artificial neural network (ANN) model is developed for the analysis, simulation, and prediction of the austenite reversion in the thermo-mechanical treatment of 304L austenitic stainless steel. The results of the ANN model are in good agreement with the experimental data. The model is used to predict an appropriate annealing condition for austenite reversion through the martensite to austeni...

In this paper, the quality factor of thermo-elastic damping in an electro-statically deflected micro-beam resonator has been investigated. The thermo-elastic coupled equations for the deflected micro-beam have been derived using variational and Hamilton principles based on modified couple stress theory and hyperbolic heat conduction model. The thermo-elastic damping has been obtained discretizi...
