Download Shape Memory Alloy Fracture as a Deployment Actuator Book in PDF, ePub and Kindle
Many applications require deployable structures to meet operational objectives such as satellites that unfurl antenna arrays. Typically, most deployment efforts involve the use of explosive and non-explosive actuators (EAs and NEAs respectively) that have implementation drawbacks such as the expense associated with special handling and the bulk encountered with mounting the devices. To mitigate EA and NEA drawbacks, the integration of shape memory alloys (SMA) as a deployment actuator was investigated. SMA specimens were heated and pulled to failure developing an environmental and structural operating envelope for application as deployment mechanisms. A Finite Element Model (FEM) was also created to model the response behavior induced during specimen testing so that modeled performance could be used in lieu of testing when integrating SMA actuators into deployment systems. Experimental results verified that SMAs can be implemented as deployment actuators. Recorded data showed that SMA fracture is possible over a wide range of temperatures and strains, filling a material performance gap not found in the literature. The obtained information allows design engineers to appropriately size SMAs given design requirements achieving the desired deployment effects. The Finite Element Model was partially successful, capable of emulating strained ambient material behavior up to approximately 6.1%. The limited response is due to lack of experimentally derived large stress and strain available for model emulation.

Download Design of Shape Memory Alloy (SMA) Actuators Book in PDF, ePub and Kindle
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.

Download Predictive Tools for the Improvement of Shape Memory Alloy Performance Book in PDF, ePub and Kindle
The superelastic and actuation performance of shape memory alloys depends greatly upon the composition and processing of the alloy, as well as the operating temperature range and stresses involved in its implementation. This thesis is in two parts. The first presents a design parameter to help classify shape memory alloys and quantify their performance as torque tube actuators. It studies the effects of crystallographic texture variation, actuator biasing stress, alloy composition, and alloy system on shape memory torque tube performance through a combination of simulation and aggregation of experimental data. Finally, a torque tube design for use in aircraft gas turbine engines is recommended based on these findings. The second part of the thesis seeks to mechanistically explain why the alloy composition effects on performance in NiTiHf shape memory alloys occur. It is hypothesized that the stabilization of martensite occurs because of the lattice mismatch strain between the “H-phase” precipitate phase, which form with the heat treatment of these alloys, and the cubic austenite phase. From this hypothesis, a model for predictions of martensite microstructures is created, and the reduction in strain energy of the formation of these microstructures is estimated.

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.
