APPLIED METAL FORMING
Including FEM Analysis
Applied Metal Forming: Including FEM Analysis describes metal
forming theory and how experimental techniques can be used to
study metal forming operations with great accuracy. For each primary
class of processes, such as forging, rolling, extrusion, wiredrawing, and
sheet-metal forming, it explains how finite element analysis (FEA) can
be applied with great precision to characterize the forming conditions
and in this way optimize the processes. FEA has made it possible to
build realistic FEM models of most metal forming processes, includ-
plex three-dimensional forming operations, in plex
products are shaped plex dies. Thus, using FEA, it is now pos-
sible to visualize any metal forming process and to study strain, stress,
and other forming conditions inside the parts being manufactured as
they develop throughout the process.
Henry S. Valberg is a professor in the Department of Engineering Sci-
ence and Materials at the Norwegian University of Science and Tech-
nology (NTNU). He began his professional career as a metallurgist at
the Royal Norwegian Air Force (LFK), and continued it at A/S Norsk
Jernverk, Mo i Rana, and then as a research scientist at SINTEF, Divi-
sion of Materials and Processes, before joining the Norwegian Institute
of Technology (NTH) as a senior lecturer in 1984 and full professor in
1994. He was a visiting professor at Denmark’s Technical University
in 1997–1998. Professor Valberg’s main fields of research are materi-
als, metal forming, experimental deformation analysis, and FEA. His
work covers all the main metal forming processes, including forging,
rolling, extrusion, drawing, and sheet-metal forming. He is the author
of more than 60 refereed journal articles and has supervised numerous
graduate students. Professor Valberg is currently a research manager
in a project run by three Norwegian panies.
