Abstract

In our previous studies, we first introduced the phase interaction energy function as a dissipation potential for the phase transformation of pseudoelasticity between austenite and martensite of shape memory alloy wires. Next, to treat both shape memory effect between twinned and detwinned martensites and the pseudoelasticity in a unified manner, we developed the phase interaction energy function and performed a thermomechanical analysis of the wire based on the developed phase interaction energy function. In the present study, the phase interaction energy function is further extended to include the effect of phase rearrangement and transformations associated with twinned and detwinned rhombohedral phases.
