Characterisation and Modelling of the Dynamic Behaviour of a Shape Memory Alloy Element

Abstract

Shape Memory Alloys (SMA) are now well recognized as potential materials for structural control. The optimized integration of some SMA devices in a mechanical structure for passive structural damping requires a predictable modelling. At first experimental and numerical studies have been performed on a CuAlBe beam under harmonic flexion, leading to a qualitative modelling based on the material thermomechanical laws. We present here a full set of experiments where the behavior of martensitic CuAlBe elements is characterized for tension in a small frequency range, typically from 0.1 to 5Hz. A dynamic modelling is then proposed and compared with the experimental results.
