Thermodynamical constitutive model for the shape memory effect due to transformation and reorientation

Shape memory effect and pseudoelasticity due to phase transformation and reorientation are modelled by specifying the free energy function and the dissipation potential. The resulting equations account for combined isotropic and kinematic hardening, adiabatic transformation, and simultaneous, coupled transformation and reorientation. Adiabatic transformation results indicate `thermal hardening' that substantially increases the final transformation stress relative to isothermal transformation.
