The paper deals with computational Simulation of rod cutting process and its experimental verifícation. Two ductile fracture criteria - Strain Limit and the Johnson-Cook criterion - are applied to cutting of cylindrical rods. The criteria are used in explicit FEM codes to simulation of fast processes. Numerical analysis of the problem was realized by the ABAQUS-Explicit FEM package and the experimental verifícation was realized in semi industrial conditions by our industrial partner, the company J-VST Brno.
