About this document
Springback Analysis in Split-Ring Test by Alina Patrascu is a document available to read on EtoBox.
This document discusses a numerical study on the influence of clearance between the die and punch on springback in the split-ring test. The study finds that: 1) Ironing during deep drawing changes the distribution of residual stresses in the cup wall, affecting ring opening values when rings are cut at different heights. 2) A smaller clearance between the die and punch (less than blank thickness) can result in smaller circumferential residual stresses, due to ironing reducing tensile stresses. 3) The
