✦ Synopsis

An investigation into the computational aspects of a multi-well mixture approach to shape memory modeling is undertaken with the goals of determining its qualitative behavior as well as its eciency in a numerical setting. A basic rate dependent model for the transformation is ®rst introduced, followed by a discussion of the steps taken to implement the constitution in discrete form. Numerical simulations demonstrate the quantitative and qualitative response of shape memory alloy structural systems to various thermal and mechanical cycles.

Ferromagnetic shape memory alloys (FSMAs) such as Ni-Mn-Ga have attracted significant attention over the last few years. As actuators, these materials offer high energy density, large stroke, and high bandwidth. These properties make FSMAs potential candidates for a new generation of actuators. The
