Metal Forming: Formability, Simulation, and Tool Design

by Chris V. Nielsen, Paulo A.F. Martins

Overview

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.

About the Author

Chris Nielsen is Associate Professor at the Technical University of Denmark, research affiliate and recipient of the F.W. Taylor Medal Award by the International Academy for Production Engineering (CIRP), recipient of the International KARL-KOLLE Prize for metal forming by the German Metal Forming Association. He is the co-author of two books, two book chapters, and has authored 60 papers in international journals and conferences. His research focuses on metal forming, metal forming tribology, resistance welding, and resistance sintering. Most research involves a combination of experimentation and numerical modeling.

Paulo Martins is Professor of Manufacturing, at the Instituto Superior Técnico, University of Lisbon, Portugal. He is also Doctor Technices Honoris Causa of the Technical University of Denmark, and a Fellow of the International Academy for Production Engineering (CIRP). He is co‐author of six books, several international patents and over 350 papers in international journals and conferences. His main research area is manufacturing, specifically numerical and experimental-based development of forming and joining by forming processes.
