The use of computational techniques is increasing day by day in the manufacturing sector. Process modeling and optimization with the help of computers can reduce expensive and time consuming experiments for manufacturing good quality products. Metal forming and machining are two prominent manufacturing processes. Both of these processes involve large deformation of elasto-plastic materials due to applied loads. In metal forming, the material is plastically deformed without causing fracture. On the other hand, in machining, the material is deformed till fracture, in order to remove material in the form of chips. To understand the physics of metal forming and machining processes, one needs to understand the kinematics of large deformation (dependence of deformation and its rate on displacement) as well as the constitutive behavior of elasto-plastic materials (dependence of internal forces on deformation and its rate). Once the physics is understood, these phenomena have to be converted to mathematical relations in the form of differential equations. The interaction of the work-piece with the tools/dies and other surroundings also needs to be expressed in a mathematical form (known as the boundary and initial conditions). In this book, the first four chapters essentially discuss the physics of metal forming and machining processes. The physical behavior of the work-piece during the processes is modeled in the form of differential equations and boundary and initial conditions.

Analysis and Optimization of Sheet Metal Forming Processes comprehensively covers sheet metal forming, from choosing materials, tools and the forming method to optimising the entire process through finite element analysis and computer-aided engineering. Beginning with an introduction to sheet metal forming, the book provides a guide to the various techniques used within the industry. It provides a discussion of sheet metal properties relevant to forming processes, such as ductility, formability, and strength, and analyses how materials should be selected with factors including material properties, cost, and availability. Forming processes including shearing, bending, deep drawing, and stamping are also discussed, along with tools such as dies, punches, and moulds. Simulation and modelling are key to optimising the sheet metal forming process, including finite element analysis and computer-aided engineering. Other topics included are quality control, design, industry applications, and future trends. The book will be of interest to students and professionals working in the field of sheet metal and metal forming, materials science, mechanical engineering, and metallurgy.

The principal aim of this text is to encourage the development and application of numerical modelling techniques as an aid to achieving greater efficiency and optimization of metal-forming processes. The contents of this book have therefore been carefully planned to provide both an introduction to the fundamental theory of material deformation simulation, and also a comprehensive survey of the "state-of-the-art" of deformation modelling techniques and their application to specific and industrially relevant processes. To this end, leading international figures in the field of material deformation research have been invited to contribute chapters on subjects on which they are acknowledged experts. The information in this book has been arranged in four parts: Part I deals with plasticity theory, Part II with various numerical modelling techniques, Part III with specific process applications and material phenomena and Part IV with integrated computer systems. The objective of Part I is to establish the underlying theory of material deformation on which the following chapters can build. It begins with a chapter which reviews the basic theories of classical plasticity and describes their analytical representations. The second chapter moves on to look at the theory of deforming materials and shows how these expressions may be used in numerical techniques. The last two chapters of Part I provide a review of isotropic plasticity and anisotropic plasticity.

In diesem Band wird die Entwicklung eines auf der Finite-Elemente-Methode aufbauenden Simulationsverfahrens für die Kalt-, Halbwarm- und Warmmassivumformung beschrieben. Das Verfahren liefert detaillierte Informationen über die plastische Werkstückdeformation sowie Wärmeentstehung und Temperaturausgleich bei Massivumformvorgängen. Die Methode basiert auf dem Markovschen Extremalprinzip und ist auf isotrope, inkompressible Werkstoffe beschränkt. Das starrplastische Fließverhalten wurde mit Hilfe des Stoffgesetzes nach Lévy-Mises erfaßt (bei technischen Vorgängen der Massivumformung können die elastischen und temperaturbedingten Formänderungsanteile gegenüber den plastischen vernachlässigt werden). Die Anwendbarkeit des Simulationsverfahrens wurde an Beispielen zum Kalt- und Warmstauchen von Stahl- und Aluminiumquadern gezeigt. Direkte Vergleiche von berechneten mit experimentellen Untersuchungsergebnissen zeigten eine gute Übereinstimmung. Dazu wurde der zeitliche Temperaturverlauf im Stauchkörper an verschiedenen Stellen meßtechnisch erfaßt und mit den Simulationswerten verglichen. Weitere Vergleiche wurden anhand von Kraft-Weg-Verläufen, Werkstückkonturen und visioplastisch bestimmten Vergleichs-Formänderungsverteilungen durchgeführt.

Metal Forming: Formability, Simulation, and Tool Design focuses on metal formability, finite element modeling, and tool design, providing readers with an integrated overview of the theory, experimentation and practice of metal forming. The book includes formability and finite element topics, including insights on plastic instability, necking, nucleation and coalescence of voids. Chapters discuss the finite element method, including its accuracy, reliability and validity and finite element flow formulation, helping readers understand finite element formulations, iterative solution methods, friction and contact between objects, and other factors. The book's final sections discuss tool design for cold, warm and hot forming processes. Examples of tools, design guidelines, and information related to tool materials, lubricants, finishes, and tool failure are included as well.
