Effect of membrane stress on surface roughness changes in sheet forming

Zhang, S; Hodgson, Peter Damian; Duncan, John; Cardew-Hall, Michael; Kalyanasundaram, Shankar

Description

Friction plays an important role in sheet metal forming (SMF) and the roughness of the surface of the sheet is a major factor that influences friction. In finite element method (FEM) models of metal forming, the roughness has usually been assumed to be constant; even though it is commonly observed that sheet drawn under tension over a tool radius results in the surface becoming shiny, indicating a major change in surface morphology. An elastic-plastic FEM model for micro-contact between a flat...[Show more]
