A jumping shape memory alloy under heat
Shape memory alloys are typical temperature-sensitive metallic functional materials due to superelasticity and shape recovery characteristics. The conventional shape memory effect involves the formation and deformation of thermally induced martensite and its reverse transformation. The shape recovery process usually takes place over a temperature range, showing relatively low temperature-sensit...
متن کاملExperimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
متن کاملSEISMIC OPTIMIZATION OF STEEL SHEAR WALL USING SHAPE MEMORY ALLOY
Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...
متن کاملDevelopment of A Monolithic Shape Memory Alloy Manipulator
The essential steps and issues in the development of a Shape Memory Alloy (SMA) based multi-degrees-of-freedom monolithic manipulator are reflected upon. The use of Direct Metal Deposition (DMD) will be described for the manufacture of the manipulator’s structure followed by the exploration of the feasibility of the “self-sensing” functionality of the structure as a basis for the manipulator’s ...
متن کاملDevelopment of a Shape Memory Alloy Actuated Robotic Hand
This paper presents the ideology of this research, which is to utilize advanced actuators to design and develop innovative, lightweight, powerful, compact, and dexterous robotic technology. The key to satisfying these objectives is the use of advanced or smart materials, such as Shape Memory Alloys (SMAs) to power the joints of a prosthetic hand, and other dexterous robotic hands. The mechanica...
