Both the Super-Elastic and Shape Memory Effect has been taken into account in this study by using SMA with high activation temperature. A Thermo-Mechanical SMA phenomenological constitutive model is used to simulate the SMA behaviour. The dynamic response data of a frame structure has been obtained from FE analysis by using the nonlinear FE software program MSC Marc. Then the frame is braced an...

Magnetic properties of electrical steel are usually measured on Single Sheet Testers, Epstein frames or ring cores. Due to the geometric dimensions and measurement principles these standardized setups, fundamental microstructural influences magnetic behavior, e.g., deformation structures, crystal orientation grain boundaries, difficult separate quantify. In this paper, a miniaturized Tester is ...

An investigation into the recovery and recrystallization of two major texture fibres, namely α γ, during annealing yielded subtle differences between two. It is reported that with thermal activation static occurs, where dislocation free sub-grains are formed tend to grow, coalesce, or bulge out. This can form new strain-free recrystallisation nuclei, coalescence bulging phenomenon depending on ...

The purpose of this study was to identify and assess dust exposure in Electrical Arc Furnaces for steel manufacturing. The major concern of steel making processes is dust generation and accumulation. The scope of this research paper focuses on different ways to improve current controls and make recommendations. In order to achieve the purpose, various goals were developed to identify the extent...

We present structural and electrical properties for p-type and n-type layers grown close to the transition between a-Si:H and nc-Si:H onto different substrates: Corning 1737 glass, ZnO:Al coated glass and stainless steel. Both crystalline fraction and dark conductivity at room temperature exhibited a transition from a-Si:H to nc-Si:H, which was clearly dependent on the substrate used. Stainless...

Classical core loss models such as two components model or modified Steinmetz model are still popular and used by engineers to loss prediction in electrical machines. They may carry to increase discrepancy between calculated and measured values. This discrepancy increases with grain-orientation and with increasing discrepancy from sinusoidal magnetisation conditions. Statistical loss model show...

The effect of uniaxial stress on iron losses M400-50A grade non-oriented electrical steel sheets cut by punching process is experimentally studied. Samples along the rolling and transverse directions having different number cutting edges are used for this purpose. Measurements carried out in range 10–100 Hz frequency sinusoidal excitations at magnetization levels under varying using a single sh...

Grain oriented steels are widely used for electrical machines and components, such as transformers reactors, due to their high magnetic permeability low power losses. These outstanding properties the crystalline structure known Goss texture, obtained by a suitable process that is well-known in widespread use among industrial producers of ferromagnetic steel sheets. One most interesting research...
