In this paper is presented a novel approach for current measurement using smart materials, magnetic shape memory (MSM) alloys. Their shape change can be controlled by the application of magnetic field or mechanical stress. This gives the possibility to measure currents by correlating the magnetic field produced by the current, shape change in an MSMbased sensor and the voltage output of a Linea...

The Ni2Mn1+xZ1−x Heusler alloys, where Z = In, Sn,Sb are attractive candidates for shape memory applications. effect is directly related to their magnetic properties. We have studied these systems by ab-initio calculations and experiments, focusing on moments exchange-bias fields. indicate that the composition dependence of total moment due competing ferromagnetic antiferromagnetic alignment be...

The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...

In this study, we aim to evaluate the shape memory effect of a Poly (Caprolactone) (PCL) (40%) and Styrene-Butadiene-Styrene (SBS) (60%) blend. Shape cycle tests are performed at different temperatures detect best recovery rate. Under appropriate temperature, blend recovers substantially its original shape. To study rate evolution, multi realized with controlled temperature. The results indicat...

In the framework of theory diffuse martensitic transitions to be based on thermodynamic and kinetic relationships mechanism magnetocaloric (MC) effect in shape memory ferromagnetic alloy crystals is theoretically analysed. The adequately describes magnetostructural transformations MC these at adiabatically applying them eliminating from magnetic field. analysis also includes magneto-anisotropic...
