DOWNLOAD EBOOKAfter a brief introduction into crystal plasticity,the fun- damentals of crystallographic textures and plastic anisotro- py, a main topic of this book, are outlined. A large chapter is devoted to formability testing both for bulk metal and sheet metal forming. For the first time testing methods for plastic anisotropy of round bars and tubes are included. A profound survey is given of literature about yield criteria for anisotropic materials up to most recent developments and the calculation of forming limits of anisotropic sheet me- tal. Other chapters are concerned with properties of workpieces after metal forming as well as the fundamentals of the theory of plasticity and finite element simulation of metal forming processes. The book is completed by a collection of tables of international standards for formability testing and of flow curves of metals which are most commonly used in metal forming. It is addressed both to university and industrial readers.

DOWNLOAD EBOOKDuctility and Formability of Metals: A Metallurgical Engineering Perspective uses metallurgical, mechanical and physical principles and concepts to explain ductility while emphasizing the influence of material microstructure on damage mechanisms. Focusing on steel, aluminum, copper, titanium and magnesium alloys, the book examines the strain hardening behaviors of these metals and alloys, the influence of strain rate and temperature, and ductile fracture mechanics. Hot plastic deformation is covered with special consideration given to its interplay with recrystallization phenomena. Other phenomena such as Dynamic Strain Ageing (DSA) and Adiabatic Shear Banding (ASB) are discussed, and metal working applications such as forging, extrusion and machining are included throughout. Methods for control of ductile cracks in metal parts resulting from rolling, forging, extrusion, drawing, and sheet metal forming are also outlined. - Provides an overview on the plastic deformation behavior and ductile fracture of steel, aluminum, copper, titanium and magnesium alloys - Illustrates the influence of microstructure on yield behavior, strain hardening of metals, and the influence of strain rate and temperature - Covers the role of the strain hardening coefficient (n), strain rate index (m), Dynamic Strain Ageing (DSA), and Adiabatic Shear Banding (ASB) - Metalworking applications are provided throughout, including forging, rolling, extrusion, wire drawing, sheet metal forming and machining

DOWNLOAD EBOOKThis important, comprehensive book examines and explains advanced methods and skills-including circle grid analysis and finite element analysis-to enhance formability measurement and analysis. Its technical foundation includes metallurgy, engineering mechanics (plasticity) and forming die surface and die component kinematics. It also studies broad stamping defects that are affected multiple variables in stamping engineering and production. The author has amassed more than 10 years of stamping experience at Ford Motor Company as a draw die specialist, project leader, stamping CAE analyst and stamping process engineer. His responsibilities at Ford have included the establishment and management of a formability lab, improvement of die performance in stamping production, draw die development, problem solving during die tryouts and launch, sheet metal performance control, stamping engineering tool development and stamping CAE. Throughout the book, emphasis is on defects severity measurement and analysis versus stamping variables, and special features include deformation characterization of stampings; structuralization of deformation fields; measurement of formability indexes; establishment of stamping process windows; and applications of the control principles of metal flow technology. Applications for the automobile industry are highlighted throughout, and are featured in a chapter dedicated to the subject.

DOWNLOAD EBOOKMetal 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. Provides fundamental, integrated knowledge on metal formability, finite element topics and tool design Outlines user perspectives on accuracy, reliability and validity of finite element modeling Discusses examples of tools, their design guidelines, tool lubricants, and tool failure Considers the role played by stress triaxiality and shear and introduces uncoupled ductile damage criteria Includes applications, worked examples and detailed techniques
