Shape memory alloys cyclic behavior: Experimental study and modeling
Article Abstract:
The cyclic behavior of sharp memory alloys (SMA) especially the influence of strain rates on three different materials is investigated experimentally. Results of a few numerical simulations show that it is highly important to care about the change of the behavior with the cycling to predict the stiffness and damping variations, and the study permits us to improve the nonlinear modeling of SMA in order to develop and optimize applications for the control and damping in civil engineering.

Seismic vibration control using superelastic shape memory alloys
Article Abstract:
Superelastic NiTi shape memory alloy (SMA) wires and bars are examined in order to determine their damping and recentering capability for applications in the structural control of buildings subjected to earthquake loadings. Results show that larger diameter bars perform well and the unique properties of SMAs help in reducing vibration response of a structure during seismic events.

Small amplitude dynamic properties of Ni(sub 48)Ti(sub 46)Cu(sub 6) SMA ribbons: Experimental results and modeling
Article Abstract:
The dynamic mechanical thermal analysis (DMTA) test is carried out at different frequencies and temperatures and the results acquired during heating and cooling process, as well as the storage modulus and loss factor values obtained is shown. The fractional derivative model is developed to simulate the heating and cooling of the SMA ribbon.
