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...

The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...

We present a combination of transient electro-thermal simulations of three-dimensional interconnect structures and the calculation of their coupled intrinsic thermo-mechanical stress distributions. For the numerical solution of the electro-thermal as well as the thermo-mechanical stress problem, we apply the finite element method. A practical example is presented where the temperature and the p...

Employing the Ginzburg-Landau phase-field theory, a new coupled dynamic thermo-mechanical 3D model has been proposed for modeling the cubic-to-tetragonal martensitic transformations in shape memory alloy (SMA) nanostructures. The stress-induced phase transformations and thermo-mechanical behavior of nanostructured SMAs have been investigated. The mechanical and thermal hysteresis phenomena, loc...
