dc.description.abstractEver since the ideal forming theory has been developed for process design purposes, application has been limited
to sheet forming and, for bulk forming, to two-dimensional steady flow. Here, application for the non-steady case was made
under the plane-strain condition. In the ideal flow, material elements deform following the minimum plastic work path (or
mostly proportional true strain path) so that the ideal plane-strain flow can be effectively described using the two-dimensional
orthogonal convective coordinate system. Besides kinematics, schemes to optimize preform shapes for a prescribed final part
shape and also to define the evolution of shapes and frictionless boundary tractions were developed. Discussions include
numerical calculations made for a real automotive part under forging.
