Abstract
A simpffied procedure for the design of SMA(Shape Memory Alloy) actuators is presented. The inter-relationship between the mechanical properties and the electrical properties that are relevant for the design of SMA actualors working under a conEtant load are clearly brought out. The dilferent conditions that arise while using an SMA actuator against o constant load has been considered. The locus of SMA acluators in relation to conventional actuators has been clartfied. The joule heating efects and power developed by the SMA actuator in relation to its weight has been also dealt with.
