Application of the finite element method to metal forming processes

Conference ·
OSTI ID:6826995
Metal forming processes are characterized by large amounts of plastic flow which comes from taking ''blanks'' or ''billets'' of elementary shape and distorting them into more useful geometries, generally more complicated. In terms of manufacturing technology, the field is divided into bulk forming and sheet forming. Bulk forming covers extrusion and plate rolling while sheet forming includes sheet metal stamping and stretch forming. Part of what is possible in the way of detailed examination of these processes is shown using modern finite element method computational tools. As an example the role of friction between the tool and the metal being formed is explored. From calculations it is evident how the effects of changes in tool and die shapes may be explored as well as how the changes in stress-strain behavior from alloying affect formability.
