“…In addition to jump phenomenon, chaos and bifurcation (Bernardini and Rega, 2005;Dos Santos and Savi, 2009;Lacarbonara et al, 2004;Machado et al, 2007a;Machado et al, 2007b;Machado et al, 2003Machado et al, , 2004Piccirillo et al, 2008Piccirillo et al, , 2009aSavi, 2015;Savi and Nogueira, 2010; were also studied in softening nonlinear dynamic systems with NiTi SMA. In sharp contrast, much less has been achieved on the experimental aspect.…”
