Abstract
In order to describe the shape memory effect, superelasticity and recovery stress due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy, a thermomechanical constitutive equation considering the volume fractions of induced phases associated with both transformations is developed. The conditions for progress of phase transformation and subloop-deformation behavior are discussed. A nonlinear thermomechanical constitutive model of polyurethane-shape memory polymer is developed to describe the thermomechanical properties such as shape fixity, shape recovery and recovery stress, by modifying a linear model. The coefficients in the model are expressed by the single exponential functions of temperature in order to describe the variation in mechanical properties of the material due to the glass transition.
