SMA nonlinear response is associated with adaptive dissipation related to their hysteretic behavior. This paper discusses the nonlinear responses of shape-memory non-ideal oscillators, based on a thermomechanical consistent model with four state variables. Two cases are investigating, namely, the case when SMA presents a large hysteresis loop and another one with less hysteresis. Computer simulations are carried out via a numerical approach showing qualitative results concerned with regular and non-regular motions.804-813engnon-ideal systemNonlinear dynamicsshape memory materialthermomechanical couplingTrabalho apresentado em evento10.1063/1.4904653Acesso aberto2-s2.0-85016608387
