Currently, there is a great interest in the study of shape memory alloy (SMA) composites, since SMA wires with a small diameter have become commercially available. Many potential uses have been found for SMA composites in shape control, vibration Active vibration and structural acoustic control of memory shape can yield stresses of 100 000 p (the yield strength of martensitic nitinol is approximately 12 000 p) as shown in Figs. 1 and 2 (Cross et al., 1969). . Substantial progress has been made in understanding the nature of the shape memory effect. A great deal of litera- ture has been published over the past 20 years presenting O3

An Overview of Nitinol:Superelastic and Shape Memory

The Shape Memory Effect. The most common demonstration of the shape memory effect is that a piece of this metal can be deformedfor example, by winding a piece of straight wire into a tight coiland then the deformation can be completely removed by heating the Analysis of the Impact Dynamics of Shape Memory Alloy A superelastic shape memory alloy is characterized by high strain capability, which is mainly related to the plateau region in the stress-strain relation due to the stress-induced martensitic phase transformation.

Effect of hysteretic properties of superelastic shape

Jan 12, 2006 · Shape memory alloys (SMAs) are characterized by unique superelastic behaviour which enables the material to recover its original shape after experiencing large deformations. This phenomenon provides ideal recentring capabilities which can be used in the passive control of structures subjected to earthquakes. Experimental investigations of building structure with a Nov 14, 2016 · With the goal to assess its effectiveness in structural vibration suppression under strong seismic excitations, this paper experimentally investigates shaking table tests of a new superelastic shape memory alloy friction damper (SSMAFD). The damper consists of pre-tensioned superelastic shape memory alloy (SMA) wires and friction devices.
