## Definitions

1. 1.

The maximum friction law demands that the friction stress is equal to the shear yield stress in the case of pressure-independent models considered,

2. 2.

The maximum friction law demands that the friction surface coincides with a stress characteristic or an envelope of stress characteristics in the case of the double-shearing model,

3. 3.

The maximum friction surface is a surface with maximum friction,

4. 4.

The strain rate intensity factor is the coefficient of the leading term in a series expansion of the quadratic invariant of the strain rate tensor in the vicinity of maximum friction surfaces.

The definition for the maximum friction law above applies at sliding.
