"Numerical simulations of Taylor test have been performed using the Johnson-Cook constitutive equation.The variation of main parameters of this equation has been studied in details. The comparison of the computed specimen profiles with experimental ones and hardness variations with computed plastic deformation suggests that there may be at least two differend mechanisms of the plastic strain."@en . .
