A Control System For Achieving Rapid Controlled Motions From Shape Memory Alloy (SMA) Actuator Wires

Acknowledgements There are many who have made contributions, both directly and indirectly to the completion of this thesis. I would like to name a few. First of all, I would like to sincerely thank my supervisor, Dr. Roy Featherstone, whose help has been enormous and whose enthusiasm has sparked my own in this wonderful work. His ideas and suggestions had frequently created jigsaw puzzles with ...

Effects of the asymmetric behavior of the shape memory alloy on nonlinear dynamic responses of thick sandwich plates with embedded SMA wires

In the present article, the dynamic behavior of sandwich plates with embedded shape memory alloy (SMA) wires is evaluated for two cases wherein (i) the stress-strain curve of the superelastic behavior of the SMA wires is symmetric and (ii) the mentioned curve is non-symmetric. A modified version of Brinson’s constitutive model is proposed and used. The high non-linearity in the behavior stems f...

Structure and thermomechanical behavior of NiTiPt shape memory alloy wires.

The objective of this work is to understand the structure-property relationships in polycrystalline NiTiPt (Ti 42.7 at.% Ni 7.5 at %Pt) with a composition showing pseudoelasticity at ambient temperatures. Structural characterization of the alloy includes grain size determination and texture analysis while the thermomechanical properties are explored using tensile testing. Variation in heat trea...
