Shape Memory Alloy Modeling and Morphing Structures
We develop constitutive models and finite elements for the thermomechanical behavior of SMA actuators. The work covers partial transformation cycles, large displacements, thermomechanical coupling and damping. These models are used for morphing structures and adaptive blades.
