METHOD FOR STUDY OF DISTRIBUTION OF DEFORMATIONS

摘要

A method for study of character of distribution of deformations at drawing includes supply of the sample, pressing with deformation measureand canting between pressing by angletill obtaining a circle in cross section. Feeding of the sample to heads for pressing is performed till the front end of the lower head comes to coincidence with a cross mark pre-applied on the sample at distance from its end equal to the value of feed ratioj.
