dc.description.abstract A systematic study of the effect of various thermomechanical model parameters on the nonlinear dynamical response of Shape Memory Oscillators is carried out in the background of theoretical predictions by the construction of behavior charts. Use is made of the Method of Wandering Trajectories, enhanced by the evaluation, as a quantitative indicator of chaoticity, of the maximum value of the normalized separation in the displacement over a fixed interval of time. It turns out that two main aspects of the model behavior are relevant for the occurrence of chaos: the slope of the pseudoelastic plateaus and the width of the hysteresis loop. It is shown that these two aspects are governed by various combinations of model parameters to be possibly controlled in the design stage in order to avoid undesired dynamic behaviors. en_US
