Abstract

Experiments were conducted to investigate the effect of the shape of Nitinol strips on shifting the natural frequency of a cantilever beam. Nitinol belongs to a group of metallic materials known as Shape Memory Alloys (SMA). Nitinol strips were attached to the cantilever beam in order to reduce the vibration of the beam upon activation. The results show that Nitinol strips with curved mem- ory are more effective than straight strips in shifting the natural frequency of the system. 1 Introduction Shape Memory Alloys (SMA) are a group of metallic materials that have the ability to return to a previous shape when subjected to heat. The SMA material used in this experiment consiste
