SMA Codes

Homogenized Energy Model (Constant Temperature)

This code uses the homogenized energy model for shape memory alloys to simulate the strain using a stress input over a constant temperature. The main simulation file is DriverSimulation.m and the main optimization file is DriverOptimization.m. Both files use the constant-temperature SMA data. The optimization driver allows for optimizing the densities only (params.optimizeAll = 0) or the densities and model parameters (params.optimizeAll = 1).
