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.Modeling and Engineering Applications Dimitris C. Lagoudas ... The device can be released in 3 ms and then reset for another actuation. ... application that exploits this behavior is the SMA spring for the continuous variable transmission in the Mercedes A class. The spring acts as a sensor that monitors the temperature and actuates a valve at a specific temperature, which changes the direction of oil flow.
