The application of shape memory alloys (SMA) as actuators in smart structures is a quickly developing field. The particular focus of this paper is on the aspects of modeling and simulation of adaptive structures with integrated SMAs using the finite element method (FEM).

A number of generic SMA actuator wire/elastic beam systems are presented first to illustrate the different ways of implementation of SMA models into COMSOL. Finally, a first step towards the simulation of an SMA-based flapping Micro Aerial Vehicle (MAV) is presented. In this paper, the modeling and simulation of an active structure, which is actuated by SMAs will be presented.
