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 ...

Modelling and experimentation of the evolution of texture in an Al-Mg alloy during earing cupping test [PDF]
, 2017 Earing and thinning are often the major manufacturing problems occur during deep drawing processes. Thinning occurs when a section of a part undergoes localised deformation, and earing is the formation of wavy edges at the open end of a drawn part that ...

Topology Driven Improvement of FDC Build Parameters [PDF]
, 1998 The likeliest failure origin for advanced ceramics parts, prepared by fused deposition, is a void from improper fill. Adequate filling of each cross-section is dependent upon the deposition toolpath.

Ear, ears, and more ears! [PDF]
Archives of Disease in Childhood, 2001 In the US this year, clinicians will write approximately 25 000 000 oral antibiotic prescriptions for acute otitis media (AOM). I thought it worthwhile to describe current management in the US, given how often clinicians diagnose AOM, the concern about appropriate use of oral antibiotics, and the European trend for not treating this condition with ...

Application of the continuum shell finite element SHB8PS to sheet forming simulation using an extended large strain anisotropic elastic–plastic formulation [PDF]
, 2012 http://link.springer.com/article/10.1007%2Fs00419-012-0620-xThis paper proposes an extension of the SHB8PS solid–shell finite element to large strain anisotropic elasto-plasticity, with application to several non-linear benchmark tests including sheet ...

Reduce the Planar Anisotropy of AA6016 Aluminum Sheets by Texture and Microstructure Control
Crystals, 2020 In order to produce a more isotropic Al-Mg-Si alloy sheet in the T4 temper, pre-annealed AA6016 hot rolled strips were cold rolled by conventional rolling, transverse rolling and an alternative rolling schedule.

Optimization of initial blank shape for square cup deep drawing using variable blank holder force
Nihon Kikai Gakkai ronbunshu, 2014 In deep drawing, area above the trimmed line is called earing. Reduction of the earing in deep drawing is one of the major issues for cost reduction. In addition, a high BHF causes tearing while a low BHF leads to wrinkling.
