modeling boundary friction of coated sheets in sheet metal
In fully plastic contact conditions where nominal contact pressure is relatively high, like in metal forming processes, individual summits join together to form contact patches. The geometry of these contact patches depends on the contact pressure, which results in load-dependent frictional behaviour. This paper describes a model that takes into account this effect, and calculates contact and Antonius H. van den Boogaard University of Twente Modeling boundary friction of coated sheets in sheet metal forming Shisode, M.

Contact mechanics of zinc coated steel sheets in contact with smooth tools are treated from the viewpoint of plastic deformation phenomena in the asperities of the coating and its matrix material. A plane strain deformation of the asperity model is proposed and analysed by using the upper bound method for the cases of non-deforming bulk materials. Evolution of real area of contact due to combined normal Nov 11, 2020 · Understanding asperity flattening is vital for a reliable macro-scale modeling of friction and wear. In sheet metal forming processes, sheet surface asperities are deformed due to contact forces between the tools and the workpiece. In addition, as the sheet metal is strained while retaining the normal load, the asperity deformation increases significantly.
