“…[10,15]). A time-integration ofD equals the total amount of dissipated energy as has been shown in [26] where thermal experiments served as sole input for (noncyclic) mechanical tension tests of NiTi wires. The simulated mechanical stress/strain relation equaled the experimentally observed one without any further model calibration.…”

“…The dissipation parameters, however, are less ''intuitive'' to be found. In [9] a formula was derived for the dissipation parameter r 1 which controls when transformation sets in (r 2 and r a are the viscous parameters which have to be adjusted such that the evolution is ''fast enough''). The formula reads…”

“…Research results suggest that the hysteresis area evolution was not related with the loading rate in a monotonic fashion. Junker et al [256] were among the first to develop a model based on the principle of the minimum of the dissipation potential, able to predict the mechanical material behaviour at full transformation using parameters derived only from DSC experiments and the caloric parts of Helmholtz free energy. Inspired by micro-mechanics, Kelly et al [257] proposed a macroscopic constitutive model capable of describing both thermally and mechanically induced transformation CHAPTER 2.…”
