This book presents a new class of metallic materials, called shape memory alloys (SMAs), as emerging materials for civil engineering applications. These materials have been used for decades in high-end fields like the aerospace and biomedical fields, and possess extraordinary properties that have attracted the attention of civil engineering researchers and practitioners for over 25 years. In this volume, based on 20 years of research findings, the author describes how SMAs started to find their way into practical applications in civil engineering. And that, like any metal, SMAs are produced in any shape, size, or form including wire, bar, and sheet, but unlike other metals, SMAs exhibit a unique ability to recover their original shape/size after being excessively deformed. Given the demand for sustainability and resilience in civil engineering applications, this book is ideal for civil engineering practitioners and materials researchers concerned with building materials and civil infrastructure.
