MAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY

Title of Document: MAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY Peng Zhao, Doctor of Philosophy, 2006 Directed By: Professor, Manfred Wuttig, Department of Materials Science and Engineering NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the mult...

SEISMIC OPTIMIZATION OF STEEL SHEAR WALL USING SHAPE MEMORY ALLOY

Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...

A jumping shape memory alloy under heat

Shape memory alloys are typical temperature-sensitive metallic functional materials due to superelasticity and shape recovery characteristics. The conventional shape memory effect involves the formation and deformation of thermally induced martensite and its reverse transformation. The shape recovery process usually takes place over a temperature range, showing relatively low temperature-sensit...
