Shape Memory Alloys (SMA) show particular properties associated to their martensitic transformation between metastable phases. Their use in dampers requires a deep knowledge of the SMA behavior and its coherence with the application requirements. In earthquakes engineering standard conditions require that, after several years or decades at rest, an excellent performance is necessary for one or two minutes, i.e., nearly 200 working oscillations. When the target is the damping of stayed cables in bridges under the wind or rain actions, a larger number of oscillations is expected per each working day. This contribution analyzes the fatigue behavior of a CuAlBe alloy (appropriate for earthquakes) and discusses the results of some available experiments on a NiTi alloy for their eventual application to stayed cables..

The development of rotary actuators is an important aspect of the engineering applications of shape memory alloys. This article reviews about a hundred references on this topic, and presents around eighty actuators driven by shape memory alloys. A classification is made according to the type of rotation (continuous or non-continuous, single or reversible direction). Different factors are then discussed, such as the characteristics of the shape memory alloy elements, the heating and cooling system for the shape memory alloy, the control of the actuator, and the output torque and stroke which can be attained. This article provides the first review focused on rotary actuators triggered by shape memory alloys, highlighting the specificities and potentialities of such actuators for new applications in the future.
