Viscoplastic Lubrication Analysis in a Metal-Rolling Inlet Zone Using Parametric Quadratic Programming

C. W. Wu, G. J. Ma, H. S. Sun
Journal: Journal of Tribology
Publisher: ASME
Article Type: Research Papers
J. Tribol. July 2005, 127(3): 605–610.

Published Online: March 16, 2005
...C. W. Wu; G. J. Ma; H. S. Sun A mathematical programming solution based on finite element method is used to analyze wall slip of viscoplastic lubrication in a metal-rolling inlet zone. Slip velocity can be directly obtained by parametric quadratic programming without an iterative process between...
