... through the modification of the hysteresis size is discussed by means of several numerical simulations. Finally, the capacity of the constitutive equations to simulate experimental data from uniaxial tests performed on SMA wires and bars of different size and chemical composition is shown. In this paper...

... due to the cycling. By introducing the thermodynamic first principle, a study of the heat equation is developed in order to predict the temperature evolution during a cyclic tensile test. Furthermore, in order to model the damping effect created by the hysteresis phenomenon and the stiffness variation...

...M. Javed Hyder A technique has been developed using the reversing dc electrical potential method to determine the mode of damage taking place during creep-fatigue interaction. It is observed that the hysteresis loop created by plotting the stress verses electrical potential gives a clear indication...

... monotonic, cyclic, and ratchetting tests. Thus hysteresis loop closure, cyclic hardening and viscoplasticity are discussed in the context of constitutive modeling for ratchetting. The cyclic tension tests reveal that very slight opening of hysteresis loops occurs, and that neither accumulated plastic strain...

... hysteresis loops robustly, is formulated by furnishing the Armstrong and Frederick model with the critical state of dynamic recovery introduced by Ohno and Wang (1993). The model is then combined with a viscoplastic equation, and the resulting constitutive model is applied successfully to simulating...
