12. Numerical example of the influence of a friction coefficient
Friction plays an important role in high-speed forming processes. Indeed, incorrect modeling of friction will inevitably lead to erroneous results in terms of geometry, stress, etc.
In the example shown in figures 21 and 22, taking into account the correct coefficient of friction perfectly simulates the incorrect filling of a die at the second station of a stamping sequence.
