VISIOPLASTICITY.
Abstract
The effort of the present investigation has taken two directions: (1) to perfect the visioplasticity method for getting steady-state streamlines by using coordinatemeasuring machines to obtain data, which are then processed by application of a computer; and (2) to reanalyze potential theory in an attempt to discover by comparison with experiments if a theoretical solution for flow theories is possible. The visioplasticity techniques permitted the attainment of steady-state streamlines and some data were processed to yield velocities, strain rates and finite strain for extrusion problems. The programs are written in such a way that they may be applied to other die configurations. Thus, it is expected that the reduction of data will be accelerated greatly once all the programs are complete. The theoretical analyses appear to show that the solution of an equivalent problem of a modified boundary shape obtained from the potential theory results in a flow net that is the best approximation to the actual flow net. This obtained solution is unique and complete. It is expected that a potential theory will be useful in rolling problems. (Author)
