On the earing in cup-drawing with non-uniform die clearance: analytical, numerical and experimental approaches

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
To minimize the earing incurred by the planar anisotropic properties of sheets, a non-uniform die clearance model was proposed for the cup drawing process.

Prediction of Earing of Hot-Rolled Al Sheets from Pole Figures

open access: yesMetals, 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

open access: yesMetals, 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.

Gene expression profiling of the inner ear [PDF]

open access: yesJournal of Anatomy, 2015
AbstractThe identification of transcriptional differences has served as an important starting point in understanding the molecular mechanisms behind biological processes and systems. The developmental biology of the inner ear, the biology of hearing and of course the pathology of deafness are all processes that warrant a molecular description if we are

Effect of the yield surface evolution on the earing defect prediction

open access: yesRevista de Metalurgia, 2023
Although the prediction of earing in the cup drawing process is considerably related to the yield surface shape, the yield surface evolution is also essential for the final ear form.

Understanding inner ear development with gene expression profiling [PDF]

open access: yesJournal of Neurobiology, 2002
AbstractUnderstanding the development of the inner ear requires knowing the spatial and temporal pattern of gene expression, and the functions of those gene products. In the last decade, hearing research has benefited tremendously from the progress of the human and mouse genome projects, as amply illustrated by the identification of many deafness genes
