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 study of deformations in dynamically and thermally loaded elastic solids has important applications in engineering. A wide literature exists on the numerical solution of dynamic thermo-elasticity problems via finite element methods (FEM). These methods include Laplace-transform FEMs and semi-discrete methods, whereby finite elements are used in space and finite differences are used in time....

A series of heteroleptic strontium complexes (1-9) using a combination of different aminoalkoxides and 2,2,6,6-tetramethyl-3,5-heptanedionate (tmhd) were prepared to examine the effect of the bulkiness and coordination ability of the aminoalkoxide ligand in these complexes as well as potential strontium precursors. All complexes were characterized by FT-IR, FT-NMR, elemental analyses, and therm...

The numerical simulation of the crack welding process is reported in this paper. The thermo-electro-structural coupled-field finite element analysis is adopted to investigate the welding process of crack surfaces. In the simulation, the pressure-dependent and temperature-dependent electrical contact conditions are considered. From the results, the crack surfaces can melt and weld together under...

In this work, internal moisture profiles obtained either by simulation or experimentally during the convective drying of resorcinol-formaldehyde gels are compared. Such a comparison constitutes an attractive way to validate drying simulation models. X-ray microtomography, a powerful 3D imaging technique, coupled to image analysis is used to determine the internal moisture profiles in a non dest...

Thermo-osmosis is a coupled phenomenon describing the fluid flow induced by thermal gradient. Recent studies on thermo-osmosis in clays and within thermal, hydraulic mechanical analysis have revealed importance of this physical processes geo-energy geo-environmental applications. This paper presents series molecular dynamics simulations interfacial water behaviour at vicinity silicate layers to...

Electro-chemical machining (ECM) allows the removal of material based on effect anodic dissolution and without mechanical contact. Thus, it avoids tool abrasion as well influencing surface quality, for instance due to formed dislocations and/or damage. Due that, ECM is a very attractive process high strength materials such titanium. The result present electric current in combination with contac...
