Shape Memory Materials

Volume is indexed by Thomson Reuters CPCI-S (WoS). This book reviews recent developments in the field of shape memory materials, which are becoming more and more important as 'smart (intelligent)' materials. The fundamental principles and properties are discussed, as well as the associated experimental and processing methods. Special emphasis is placed on the present, and potential future, applications of SMMs. Superelastic wires are already being used for the antennae of cellular phones, and medical stents and guide wires promise to become big business as well. Rapid progress is also being made in fundamental aspects, such as the kinetics of martensitic transformations, premartensitic behavior, aging problems, thin-film SMA, etc. Moreover, new experimental techniques are becoming available: such as imaging plane, TEM with energy filter, AFM, grazing-angle x-ray reflection, etc.

The book will be of interest to graduate students, engineers, scientists and designers who are working in the field of electric and mechanical engineering, industries, medical engineering, aerospace engineering, robots, automatic machines, clothes and recycling for research, design and manufacturing.

Shape Memory Alloy Engineering introduces materials, mechanical, and aerospace engineers to shape memory alloys (SMAs), providing a unique perspective that combines fundamental theory with new approaches to design and modeling of actual SMAs as compact and inexpensive actuators for use in aerospace and other applications. With this book readers will gain an understanding of the intrinsic properties of SMAs and their characteristic state diagrams, allowing them to design innovative compact actuation systems for applications from aerospace and aeronautics to ships, cars, and trucks. The book realistically discusses both the potential of these fascinating materials as well as their limitations in everyday life, and how to overcome some of those limitations in order to achieve proper design of useful SMA mechanisms. Discusses material characterization processes and results for a number of newer SMAs Incorporates numerical (FE) simulation and integration procedures into commercial codes (Msc/Nastran, Abaqus, and others) Provides detailed examples on design procedures and optimization of SMA-based actuation systems for real cases, from specs to verification lab tests on physical demonstrators One of the few SMA books to include design and set-up of demonstrator characterization tests and correlation with numerical models

Alloy Materials and Their Allied Applications provides an in-depth overview of alloy materials and applications. The 11 chapters focus on the fabrication methods and design of corrosion-resistant, magnetic, biodegradable, and shape memory alloys. The industrial applications in the allied areas, such as biomedical, dental implants, abrasive finishing, surface treatments, photocatalysis, water treatment, and batteries, are discussed in detail. This book will help readers solve fundamental and applied problems faced in the field of allied alloys applications.

Part 3 deals with the applications of shape-memory alloy and polymer such as the development of application model in engineering filed, the smart vortex generator for aircraft, the smart morphing flap driven by SMA wires and the development of application models of SMA brain spatula in medical engineering filed, the working support device in nursing care field and the energy conversion teaching material in education. This book will be interested to graduate students, engineers, materials scientists and designers who are working in the field of mechanical and electric engineering, medical engineering, nursing care technology, aerospace engineering, robots, automatic machines, clothes and recycling for research, design, manufacturing and fabrication.

This book provides a working knowledge of the modeling and engineering applications of shape memory alloys (SMAs), beginning with a rigorous introduction to continuum mechanics and continuum thermodynamics as they relate to the development of SMA modeling.Modern SMAs can recover from large amounts of bending and deformation, and millions of repetitions within recoverable ranges. SMAs are used in the medical industry to create stents, in the dental industry to create dental and orthodontic archwires, and in the aerospace industry to create fluid fittings. The text presents a unified approach to the constitutive modeling of SMAs, including modeling of magnetic and high temperature SMAs.
