Studi tentang smart materials cukup menyita perhatian dalam beberapa tahun terakhir, salah satunya yaitu tentang Shape Memory Alloys (SMA). Banyak penelitian yang telah dilakukan untuk mengembangkan SMA menggunakan paduan Ni-Ti, namun karena paduan terseb... see more

In this paper, a shape memory alloy (SMA) actuated subcarangiform robotic fish has been demonstrated using a spring based propulsion mechanism. The bionic robotic fish developed using SMA spring actuators and light weight 3D printed components can be empl... see more

A shape memory alloy (SMA) bimorph actuator is a composite structure composed of flexible polyimide substrate and SMA thin film deposited using thermal evaporation technique. In this work, the substrate thickness in the range of 25 - 75 mm was selected fo... see more

A configurable multi-segment morphing system for a micro air vehicle (MAV) is presented in this study. One of the novelties is the development of an adaptive control allocation algorithm that provides fast, simultaneous and independent operation of four m... see more

The optimal design and analysis of hot water actuated shape memory alloy spring is presented. Smart materials exhibit special properties that make them a preferred choice for industrial applications in many branches of engineering. The serviceable propert... see more

Several efforts were made over the years to control vibration of structural components made of composite materials. This paper consists of study on effect of using shape memory alloy (SMA) to increase the damping of glass fiber reinforced plastic (GFRP) c... see more

Quaternary Ni50FexMn30-xGa20 (x = 2.5, 5, and 15) and Ni45Fe5Mn30Ga20 alloys based on modification of ferromagnetic shape memory alloy ternary Ni50Mn30Ga20 composition prepared by vacuum arc melting and subsequent heat-treatment were investigated to under... see more

Ferromagnetic shape memory Ni50Mn30Ga15Al5-xBx (x = 0, 1, and 4) alloys were prepared by vacuum arc melting and subsequent heat-treatment as well as by melt spinning to investigate the effect of trivalent element additions in ternary Ni-Mn-Ga alloys. The ... see more

Frequent coast up/coast down operations of rotating shafts in the power and aerospace industry expose the flexible rotors to the risk of fatigue failures. Resonant vibrations during passage through critical speeds induce large stresses that may lead to fa... see more
