Экспериментальные исследования по пластической осадке между неподвижными стенками тонких полос в форме прямоугольника и сектора

This paper describes experiments and analysis on the upsetting between approaching rigid plates of a thin plastic sample, limited fixed walls and originally shaped rectangle or sector. Fixed wall located along the long rectangle sides and along the radial sector boundaries. It describes the definition of experimental laws, which allows to choose the corresponding mathematical model.
