The authors keep both disciplines in mind by giving readers sufficient background to apply to their particular situation, then working through the details in static and quasistatic contact problems, dynamic contact problems, and dynamic contact problems with Coulomb friction.
A Coulomb friction model is assumed on both the flank and rake faces, and the friction constants on both faces of the tool are predicted.
In the first phase, Coulomb friction generates heat at the interface, raising its temperature to the point at which the polymer can undergo viscous flow.
The sliders are nonlinear elements that implement the Coulomb friction model with a predetermined normal force and coefficient of friction resulting in a break-free force [f.
