Two-way Antagonistic Shape Actuation Based on the One-way Shape Memory Effect
The stress created by the austenite transformation of mechanically constrained NiTi shape memory alloys (SMAs) significantly exceeds that required to deform (detwin) its low temperature martensitic phase. The one-way shape memory effect can therefore be used to create antagonistic, fully reversible flexural shape morphing structures by assembling opposing pairs of linear contractile SMA actuato...
متن کاملTwo-way shape memory effect of a TiNiHf high temperature shape memory alloy
The two-way shape memory effect in a Ti36Ni49Hf15 high temperature shape memory alloy (SMA) has been systematically studied by bending tests. In the TiNiHf alloy, the martensite deformation is an effective method to get two-way shape memory effect even with a small deformation strain. When the TiNiHf alloy is deformed at a full martensite state, the deformation mechanism is the martensite orien...
متن کاملCombined One-Way and Two-Way Shape Memory in a Glass-Forming Nematic Network
Past research in the field of shape memory polymers has led to significant advancements in the areas of so-called one-way and two-way (reversible) shape memory. While one-way shape memory polymers allow indefinite fixing of a temporary shape until triggered thermally to recover to an equilibrium shape, twoway shape memory polymers feature muscle-like contraction on heating and expansion on cool...
متن کاملEffect of Electrical Current on Nitinol Medical Staples Shape Memory
Medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .It is achievable by shape memory effect. For this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. Then shape memory effect was induced...
