This book discusses the engineering applications of finite element analysis. In the past few years, Finite Element Analysis (FEA) has been refined into an important and necessary technology in the modeling and simulation of several engineering systems. This book includes contributions made by professionals from international scientific organizations. It compiles authentic and interesting research studies on the applications of FEA in some major areas of mechanical engineering like fluid mechanics and heat transfer, machine elements evaluation and design, machining and product design, wave propagation and failure evaluation, and structural mechanics and composite materials. This book presents an overview of contemporary research activities across the globe in this area and will be beneficial to a large number of researchers. The introductions, data and references provided in the book will help the readers learn more about this subject.
