The Thermomechanical Modeling for Shape Memory Alloys
The shape memory alloys are materials that can change their shape by applying thermomechanical treatments. In order to design SMA materials, the stress-strain-temperature relationship is necessary. Modeling the constitute behavior of these materials supposes a few phenomenological models that can provide a quick and reasonable approach to assess the behavior of SMA. The proposed constitutive equation expresses well the properties of the shape memory effect, pseudoelasticity and recovery stress.
