Prediction of Earing of Cross-Rolled Al Sheets from {h00} Pole Figures [PDF]
Metals, 2020 The plastic anisotropy of rolled Al sheets is the result of a crystallographic texture. It leads to the formation of uneven cup heights during deep-drawing, which is called earing.

Prediction of Earing of Hot-Rolled Al Sheets from Pole Figures [PDF]
Metals, 2021 The formation of uneven cup heights during deep drawing is called earing. This phenomenon is caused by the planar anisotropy of formability in sheets, which is the result of crystallographic texture.

Earing Reduction by Varying Blank Holding Force in Deep Drawing with Deep Neural Network
Metals, 2021 In the present study, we propose a novel method of varying blank holding force (BHF) with the segmental blank holder and investigated its influence on the earing reduction in the circular deep drawing process of an aluminum alloy sheet.

Prediction of earing of aluminium sheets from {h00} pole figures [PDF]
European Journal of Mechanics, A/Solids, 2020 Earing of deep drawn cups is a result of non-uniform formability caused by crystallographic anisotropy. The prediction of earing is of interest since the rise of the rolling process.

Achievements of Nearly Zero Earing Defects on SPCC Cylindrical Drawn Cup Using Multi Draw Radius Die
Metals, 2020 In recent years, the old-fashioned cylindrical cup shapes are still widely used, and there are many defects which could not be solved yet. In the present research, the classical earing defects, which are mainly caused by the material mechanical property ...

Simulation of earing behaviors in bake hardening steel exhibiting a strong off-γ-fiber component
International Journal of Solids and Structures, 2012 Analytical theory and a crystal plasticity finite element method (CPFEM) were used to simulate the earing profiles of drawn cups of bake hardening (BH) steel. The two approaches successfully predicted the earing profiles.
