Forming Limit of Holed Dome in Two-Stage Stretch Forming

, 2010
This paper deals with the accurate prediction of forming limit of a dome with a circular hole in two-stage stretch forming. Since this two-stage forming is a process of non-proportional deformation, a fracture criterion, which is capable to predict ...

Aluminum Alloy Sheet-Forming Limit Curve Prediction Based on Original Measured Stress–Strain Data and Its Application in Stretch-Forming Process

Metals, 2019
A new method, by directly utilizing original measured data (OMD) of the stress−strain relation in the Marciniak−Kuczynski (M−K) model, was proposed to predict the forming limit curve (FLC) of an aluminum alloy sheet.
