Abstract
This paper presents an extension of the authors' previous analyses on the one-dimensional pseudoelastic theory of shape memory alloys (SMA), in which an interaction energy has been introduced to represent the energy dissipation during the phase transformation. From the equilibrium condition of the two-phase state, we show that the partial derivative of the interaction energy with respect to the phase fraction represents the thermodynamic driving force for the phase transformation. Two functions for the interaction energy are derived from the assumptions about the driving force of the equilibrium transformation. Using this interaction energy, we also examine the stability of equilibrium state and the formation of subloops due to incomplete transformations. Analytical predictions by the proposed theory agree well qualitatively with available experimental observations.
