Shape memory alloys (SMAs) are exploited in several innovative applications such as biocompatible actuators experiencing up to large number of cyclic loads. However, the description of the SMA cyclic response is still incomplete. The present work is devoted to propose a 3D model based on the thermodynamical coupling of different strain mechanisms such as the forward and reverse phase transformation, the martensitic reorientation, the transformation-introduced plasticity and fatigue damage.
