For glass on glass 0 4.
Coefficient of friction sheet metal.
By considering the influence of the bending boundary friction model was coming into existence to predict area of contact at punch face and coefficient of friction.
For rubber on tarmac close to 1 0.
This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3d digital image correlation 3d dic to track the deformation.
The coefficient of friction is the ratio of a force to a force and hence has no units.
Static friction is friction between two or more solid objects that are not moving relative to.
The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes.
To determine frictional coefficient for stretching forming 14 in sheet metal a friction test is developed.
For polished oiled metal surfaces less than 0 1.
The ratio between the force of friction and the contact force between the two moving objects is represented by a coefficient of friction ยต whose value will depend on the tribology system itself and the forming process such as temperature of the sheet ram velocity contact pressure and the strains in the sheet.
