WebJun 20, 2008 · Numerical study of strain-rate effect in cold rolls forming of steel. J. Falsafi, E. Demirci, V. Silberschmidt. Materials Science. 2013. Cold roll forming (CRF) is a well-known continuous manufacturing process, in which a flat strip is deformed by successive rotating pairs of tools, without changing the material thickness. WebIn this article an arbitrary Lagrangian–Eulerian (ALE) formulation for modelling cavitation in elastohydrodynamic lubrication (EHL) is derived and applied to line contact geometry. The method is developed in order to locate the position of cavitation onset along the length of the contacting region which gives the transition from liquid to vapour in the fluid. The ALE …
