Phenomenology of Shape Memory Alloys
2015The strong demand for high performance structural and mechanical systems for aerospace, defense, and advanced manufacturing industries has promoted the evolution of advanced materials. Materials cannot respond to changes of the surrounding environment and are not able to operate under the service conditions for which they are not optimally designed ...

Shape memory alloy microactuators
Sensors and Actuators A: Physical, 1990Abstract Shape memory alloys (SMA) have been investigated as transducing materials for the development of actuators for robotic end-effectors. In this paper, basic concepts on the design and development of SMA actuating systems for robotic applications are discussed. The thermomechanical characterization of the SMA material is the basis on which the

Shape Memory Alloys and Collisions
2016We consider a solid, for instance a car, colliding a shape memory alloy solid, for instance a guard-rail. We address this problem assuming the collision is instantaneous. For a given percussion, the velocity of the shape memory alloy solid are predicted by the theory in agreement with the physical sense.

Nanostructured Shape Memory Alloys: Composite Materials with Shape Memory Alloy Constituents
2004Abstract : Composite materials are critical for many engineering applications because of the resultant properties that arise from the combination of dissimilar constituent materials. A particularly exciting class of constituent materials is shape memory alloys (SMAs), which continue to be explored because of their unique superelastic capabilities ...

Shape memory is the ability of a material to remember its original shape, either after mechanical deformation (one-way effect) or by cooling and heating (two-way effect). This phenonemon is based on a structural phase transformation, which is diffusionless and connected with large amounts of homogeneous shear. It is known as martensitic transformation.

Shape memory alloys are mixtures of many martensites and of austenite. The composition of the mixture varies: the matensites and the austenite transform into one another. These phase changes can be produced either by thermal actions or by mechanical actions.

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">A shape memory alloy engine has been developed for the purpose of extracting the mechanical energy from a small difference in temperature. The engine is mainly composed of two pulleys (high temperature and low temperature) and single belt made of the nickel titanium shape memory alloy.
