Abstract

Most of shape memory alloys (SMAs) are functional intermetallic. They are now practically being used for couplings, actuators, medical guide wires etc. And are hopeful candidates for smart materials, which already exist. Several papers review the latest developments in the modelling of SMAs constitutive behavior. The basic properties of SMAs are including the shape memory effect, pseudoelasticity, as well as other properties such as the acquired and two-way shape memory effect, damping capacity and fatigue life. This paper focus on the modelling of SMAs coil spring actuators, which are used as artificial muscle for its light weight and large deformation. In order to obtain the required force, the shear modulus method has been used in the modelling process. And the parameters of SMAs coil spring can be determined. The theoretical analysis accords well with experiment results.
