Two dimensional mathematical model of shape memory alloy and intelligent SMA-CAD

A generalized mathematical model for a shape memory alloy in a two-dimensional field is formulated, and the alloy's characteristics are calculated numerically. Solid mechanics and thermodynamics of phase transformations are used in the model, which can be used to estimate not only the two-dimensional distribution of the stress but also the transformation ratio of any SMA device. This model is used in an intelligent CAD system for designing and simulating micro/macro SMA devices.<
