Pseudoelasticity Of Shape Memory Alloys

Pseudoelasticity of Shape Memory Alloys: Theory and Experimental Studies is devoted to the phenomenon of pseudoelasticity (superelasticity) exhibited by shape memory alloy materials. It provides extensive introductory content on the state-of-the-art in the field, including SMA materials development, definition of shape memory effects, and discussions on where shape memory behavior is found in various engineering application areas. The book features a survey of modeling approaches targeted at reliable prediction of SMA materials’ behavior on different scales of observation, including atomistic, microscopic, mezoscopic, and macroscopic. Researchers and graduate students will find detailed information on the modern methodologies used in the process of building constitutive models of advanced materials exhibiting complex behavior. Introduces the phenomenon of pseudoelasticity exhibited by shape memory alloy materials Features a survey of modeling approaches targeted at reliable prediction of SMN materials' behavior on different scales of observation Provides extensive coverage of the state-of-the-art in the field Ideal reference for researchers and graduate students interested in the modern methodologies used in the process of building constitutive models of advanced materials

The aim of this book is to understand and describe themartensitic phase transformation and the process of martensiteplatelet reorientation. These two key elements enable the author tointroduce the main features associated with the behavior ofshape-memory alloys (SMAs), i.e. the one-way shape-memory effect,pseudo-elasticity, training and recovery. Attention is paid in particular to the thermodynamical frame forsolid materials modeling at the macroscopic scale and itsapplications, as well as to the particular use of such alloys– the simplified calculations for the bending of bars andtheir torsion. Other chapters are devoted to key topics such as theuse of the “crystallographical theory of martensite”for SMA modeling, phenomenological and statistical investigationsof SMAs, magneto-thermo-mechanical behavior of magnetic SMAs andthe fracture mechanics of SMAs. Case studies are provided on thedimensioning of SMA elements offering the reader an additionaluseful framework on the subject. Contents 1. Some General Points about SMAs. 2.

This book consists of two chapters. The first chapter deals with the thermomechanical macroscopic theory describing the transformation and deformation behavior of shape memory alloys. The second chapter deals with the extensive and fundamental review of the experimental works which include crystallography, transformations and mechanical characteristics in Ti-Ni, Cu-base and ferrous shape memory alloys.

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.

This book focuses on smart materials and structures, which are also referred to as intelligent, adaptive, active, sensory, and metamorphic. The ultimate goal is to develop biologically inspired multifunctional materials with the capability to adapt their structural characteristics, monitor their health condition, perform self-diagnosis and self-repair, morph their shape, and undergo significant controlled motion.

A comprehensive account of shape memory materials, now available in paperback.

This book commemorates the 75th birthday of Prof. George Jaiani – Georgia’s leading expert on shell theory. He is also well known outside Georgia for his individual approach to shell theory research and as an organizer of meetings, conferences and schools in the field. The collection of papers presented includes articles by scientists from various countries discussing the state of the art and new trends in the theory of shells, plates, and beams.
