Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic approach to realizing NiTi shape memory alloy actuation, and is aimed at science and engineering students who would like to develop a better understanding of the behaviors of SMAs, and learn to design, simulate, control, and fabricate these actuators in a systematic approach. Several innovative biomedical applications of SMAs are discussed. These include orthopedic, rehabilitation, assistive, cardiovascular, and surgery devices and tools. To this end unique actuation mechanisms are discussed. These include antagonistic bi-stable shape memory-superelastic actuation, shape memory spring actuation, and multi axial tension-torsion actuation. These actuation mechanisms open new possibilities for creating adaptive structures and biomedical devices by using SMAs.

This book was released on 2013-12-10 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The giant magneto-strain effect in Ni-Mn-Ga alloys is particularly attractive for actuator applications. Two different approaches are being pursued to develop MSM microactuators. To observe large deflections of Ni-Mn-Ga microactuators, the material should be exhibiting low twinning stress and large magnetic anisotropy. In addition, design rules and boundary conditions for operating the Ni-Mn-Ga actuator material are having significant importance for evolution of performance characteristics.
Download or read book Design of Shape Memory Alloy SMA Actuators written by Ashwin Rao and published by Springer. This book was released on 2015-05-08 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This short monograph presents an analysis and design methodology for shape memory alloy (SMA) components such as wires, beams, and springs for different applications. The solid-solid, diffusionless phase transformations in thermally responsive SMA allows them to demonstrate unique characteristics like superelasticity and shape memory effects. The combined sensing and actuating capabilities of such materials allows them to provide a system level response by combining multiple functions in a single material system. In SMA, the combined mechanical and thermal loading effects influence the functionality of such materials. The aim of this book is to make the analysis of these materials accessible to designers by developing a "strength of materials" approach to the analysis and design of such SMA components inspired from their various applications with a review of various factors influencing the design process for such materials.

Microprocessors and computers used to be the main limiting element in most information processing systems. But thanks to the enonnous progress in the microelectronics industry, most information analysis tasks can be processed in real time. The data has to be acquired by the processor in some form and processed and used to produce some useful function in the real world.

Download or read book Engineering Aspects of Shape Memory Alloys written by T W Duerig and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering Aspects of Shape Memory Alloys provides an understanding of shape memory by defining terms, properties, and applications. It includes tutorials, overviews, and specific design examples—all written with the intention of minimizing the science and maximizing the engineering aspects. Although the individual chapters have been written by many different authors, each one of the best in their fields, the overall tone and intent of the book is not that of a proceedings, but that of a textbook. The book consists of five parts. Part I deals with the mechanism of shape memory and the alloys that exhibit the effect. It also defines many essential terms that will be used in later parts. Part II deals primarily with constrained recovery, but to some extent with free recovery. There is an introductory paper which defines terms and principles, then several specific examples of products based on constrained recovery. Both Parts III and IV deal with actuators. Part III introduces engineering principles while Part IV presents several of the specific examples. Finally, Part V deals with superelasticity, with an introductory paper and then several specific examples of product engineering.

Download or read book position control with magnetic shape memory actuators written by Leonardo Riccardi and published by Lulu.com. This book was released on 2012-02-26 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic shape memory alloys are promising materials for several applications, such as positioning systems. This book presents the main features of those materials, and then addresses the problem of controlling magnetic shape memory positioning actuators. Two control approaches are introduced, namely a PID control and an adaptive control based on adaptive hysteresis compensation. They are able to handle the presence of hysteresis in the input-output characteristic. The adaptive approach also handles the temperature-dependent behaviour of the nonlinearity. Experimental results performed on several actuator prototypes demonstrate the effectiveness of the control approaches presented here.

From automotive and aeronautical to biomedical and robotics, engineers are constantly developing actuating devices that are adapted to their particular needs in their particular field, and actuators are used in almost every field of engineering that there is. This volume not only lays out the fundamentals of actuators, such as how they operate, the different kinds, and their various applications, but it also informs the engineer or student about the new actuators that are being developed and the state-of-the-art of actuators. Edited and written by highly experienced and well-respected engineers with a deep understanding of their subject, there is no other volume on actuators that is more current or comprehensive. Whether as a guide for the latest innovations in actuators, a refresher reference work for the veteran engineer, or an introductory text for the engineering student, this is a must-have for any engineer’s or university’s library. Covering the theory and the practical applications, this breakthrough volume is a “one stop shop” for any engineer or student interested in actuators.

This book was released on 2022-05-18 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shape Memory Composites Based on Polymers and Metals for 4D Printing is a thorough discussion of the physics and chemistry behind this developing area of materials science. It provides readers with a clear exposition of shape-memory-composite (SMC) preparation techniques for 3D and 4D printing processes and explains how intelligent manufacturing technology may be applied in fields such as robotics, construction, medical science, and smart sensors. The book covers fundamental background knowledge on the synthesis of shape memory polymers (SMPs) and shape memory alloys (SMAs), and additive manufacturing techniques. Polymers and metals and their roles in 4D printing are dealt with separately, and applications of 4D printing are treated in their own chapter. The different alloy compositions and nanoparticle fillers in polymer composites are examined in detail, along with the key mechanisms involved in their processing. Hybrid nanofillers and synergistic composite mixtures, which are either in extensive current use or have shown promising outcomes in the field of 4D printing, are thoroughly discussed. Differences between these novel SMCs and traditional metal alloys, organic and inorganic composites are presented, and means by which they can improve mechanical properties that are triggered by external sources like magnetic field, temperature, and pH of solvent, are set out. This book provides practitioners, industrial researchers, and scholars with a state-of-the-art overview of SMP/SMA synthesis, additive manufacturing, modification in synthesis of SMCs for 4D printing, and their likely future applications.
