On the Formation of a Sticking Layer on the Bearing during Thin–Section Aluminium Extrusion
Published in 2009
This paper describes the use of COMSOL Multiphysics® to determine the shear layer thickness in thin–section aluminum extrusion, based on the minimum work criterion. The studied two aluminum alloys are AA 6063 and AA 7020. The results show that a continuous shear layer featuring shear localization due to localized thermal softening is not possible to form under typical thin–section aluminum extrusion conditions.
