Taylor series to solve friction problems [Technique de perturbations pour les problèmes de frottement]

摘要

Thin metallic sheet transportation appears in numerous manufacturing processes such as continuous annealing, levelling or galvanization. It involves various nonlinear phenomena and, in particular, contact with friction. We develop a numerical method to solve this kind of mechanical problem, using shell finite elements and the Asymptotic Numerical Method (ANM). This article focuses on the treatment of the friction equations with ANM.
