... influencing sheet metal forming, we should recall that a sheet metal forming operation can always be, from the conceptual point of view, divided in two stages: • A first stage where the volume of ... using less metal sheet, thanks to a removal of an excessive run-off. At last, run-offs around the problem area can also be improved, via the use of evolutionary radii instead of constant ... to the blank and to the run-off can be seen on this shape. • The distribution graphs of a certain number of quantities typical to the analysis of the sheet metal forming. These are plotted on...
