Aluminum Foil Forming Limitation Test and Numerical Simulation

doi:10.16183/j.cnki.jsjtu.2018.09.011

Abstract

Abstract: Thinner aluminum foil brings bigger challenge to its forming performance, so in this paper, no-damage UV printing technology was applied to marking grid in specimens, and an FLD test for 0.11 mm 8011-H22 aluminum foils was successfully launched. Because aluminum foil deformed very little in the width direction under the big width-thickness ratio and the effect of friction, only the right part of FLD could be obtained. Then the finite element simulation of rigid model bulging test was established, and the left part of FLD could be further completed based on the “strain acceleration” failure criteria. A complete FLD was then finally established.

Key words: UV printing technology, aluminum foils, forming limit diagram (FLD), strain acceleration, finite element method
