Drawbead Forces in Sheet Metal Forming
TL;DR: In this paper, the bending deformation component was isolated by replacing the shoulders and bead of the drawbead by rollers, which reduced the friction to a negligible value and good agreement was found between the measured and calculated frictional components.
Journal ArticleDOI
The influence of surface roughness on wear
R.G. Bayer,J.L. Sirico +1 more
TL;DR: In this article, a series of wear experiments utilizing a ball-plane configuration was performed to determine the influence of both the magnitude and anisotropy of the surface roughness on wear.
Journal ArticleDOI
Evaluating the GMR-Limiting Dome Height Test as a new measure of press formability near plane strain
TL;DR: The Limiting Dome Height test (LDH) as discussed by the authors was proposed to predict formability since this test modifies specimens to produce the same strain state at failure as found in a particular stamping.
Journal ArticleDOI
Speed effects in drawbead simulation
TL;DR: In this article, the effects of drawing speed on galvannealed, electrogalvanized, and hot-dip galvanized sheets, with a cold-rolled steel serving as reference, were explored in drawbead simulation tests.
