Influence of hysteresis loop shape on the nonlinear dynamics of shape memory alloy oscillator excited by non-ideal energy sources
(2014-12-10)
The dynamical response of systems with shape memory alloy (SMA) presents a different behavior due to their nonlinear characteristic. SMA nonlinear response is associated with adaptive dissipation related to their hysteretic ...
Phase transformation and shape memory effect of a Cu-Al-Ni-Mn-Nb high temperature shape memory alloy
(Elsevier Science, 2016-04)
The microstructure, phase transformation and shape memory effect of the high temperature shape memory alloy Cu-11.4Al-3.2Ni-3Mn-0.5 Nb (wt%) were investigated for the first time. The shape recovery ratio can achieve 73% ...

Shape memory epoxies based on networks with chemical and physical crosslinks
(Elsevier, 2011-03-30)
Epoxies are an important family of shape memory polymers (SMP) due to their excellent stability and thermo-mechanical endurance and the high values of shape fixity and shape recovery. Actuators based on these materials can ...
Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part I: Ideal energy source
(Springer, 2009-01-01)
In this paper, an optimal linear control is applied to control a chaotic oscillator with shape memory alloy (SMA). Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, ...
On a nonlinear and chaotic non-ideal vibrating system with shape memory alloy (SMA)
(Polish Soc Theoretical & Applied Mechanics, 2008-01-01)
In this paper, we present nonlinear dynamic behaviour of a system which consists of a mass connected to a rigid support by a shape memory alloy (SMA) element and a damper. In order to disturb the system, a DC motor with ...
