Since the equivalent strain rate has a great effect of material properties, it is of important to reveal the dependence of the strain rate intensity factor on parameters characterizing material models.
Since the equivalent strain rate significantly influences the evolution of material properties, this theoretical result is in qualitative agreement with many experimental results demonstrating that there is a material layer near friction surfaces within which material properties are quite different from those in the bulk [2 - 8].
