Strain determination by the method of phisical discretization

Abstract

The determination of working piece deformation state at bulk metal forming in open dies of axisymetrical pieces has been carried out in this paper. Preparation pieces made in appropriate way have been used in investigations. Preparation pieces are made out of segments, thus they are physically discreeted, so that such a method is said to be the method of physical discretization (MPD). By a suitable mechanical and chemical forming it is possible to obtain a deformed image of a meridial cross-section and determine a deformation state, which has been done. Finally, the results and given directions for further investigations in the sense of improving the method have been analyzed.
