in this paper the response of cantilevered reinforced concrete (rc) beams with smart rebars under static lateral loading has been numerically studied, using finite element method. the material used in this study is superelasticshape memory alloys (se smas) which contains nickel and titanium elements. the se sma is a unique alloy that has the ability to undergo large deformations and return to t...

Since the introduction of nickel titanium (NiTi) to field endodontics, it paved way for fast and reliable root canal instrumentation. Rotary instruments are solely manufactured from NiTi alloy, due its favorable mechanical physical properties such as flexibility cutting efficiency. The main problem with rotary is their high fatigue susceptibility, unexpected incident instrument separation insid...

Exploration of new ferroic (ferroelectric, ferromagnetic or ferroelastic) materials continues to be a central theme in condensed matter physics and to drive advances in key areas of technology. Here, using thin-film composition spreads, we have mapped the functional phase diagram of the Ni-Mn-Ga system whose Heusler composition Ni(2)MnGa is a well known ferromagnetic shape-memory alloy. A chara...

Intelligent, autonomous, shape-controllable structures based on Shape Memory Alloy materials have the potential to provide advanced aircraft and spacecraft systems with the ability to morph, or change their shape for the purpose of optimizing performance. An important aspect of this capability is control of the shape modifications themselves, which benefits from accurate models of the voltage/c...

The nickel-titanium (Ni-Ti) alloys used in endodontics contain 56% Ni and 44% Ti. The 2 unique features related to clinical dentistry (i.e., shape memory effect and superelasticity) are due to the transition from austenite to martensite in Ni-Ti alloy. When a superelastic Ni-Ti alloy undergoes a low tensile loading, normal elastic behavior occurs. In fact, at higher tensile loads, the elastic s...
