Abstract

A plastic stress analysis was made of the conical cup problem using the maximum shear stress criterion. Limiting diameter ratios were determined for both perfect lubrication and friction conditions. A fixture was designed and constructed for 6.0- in. (15.24-cm) diameter blanks up to 0.20 in. (0.508cm) in thickness. Experiments were conducted with strains determined by the circular grid method. © 1983 by ASME.
