Because of its smart characteristics with shape memory effect and superelasticity, shape memory alloyused in sensors, actuators, and microelectromechanical systems (MEMS), is regarded as an emergingapplied material with high added value by its additional biomedical compatibility for medical devices andimplants. Therefore, developing the production technologies of shape memory alloy and its applicationsis meaningful not only for the country advancing the era of “island of biomedical technologies” but alsofor the precision industries and the metal industries in this island to improve their output value. For thisreason, this proposal is aimed to investigate the forming properties of shape memory alloy inthermomechanical forming process according to its potential huge requirement in biomedical devices andMEMS industries. Consequently, the corresponding research works for the application of shape memoryalloy will intensively be threw into and its application spectrum will therefore be enlarged.This study is proposed as a three-year project to investigate the thermomechanical forming propertiesof shape memory alloy via material test, finite element analysis, and thermomechanical forming test -respectively for each year. In this study, experiments are induced to investigate the mechanicalcharacteristics of shape memory alloys in emphasis on thermomechanical properties. A finite elementmodel is built and executed to simulate these experiments as well. Additionally, an analytical model willbe proposed in this study to describe the metalworking properties of shape memory alloy inthermomechanical forming process in association of experiments, so that the thermomechanical formingmechanism of shape memory alloy could be also examined in this proposal. Its results would besignificantly referred for industrial applications.
