AB  - Cleavage fracture of commercial medium-carbon V-microalloyed forging steel with predominantly acicular ferrite structure was studied by means of fourpoint bending testing at liquid nitrogen temperature in conjunction with finite element analysis. Both two-dimensional and three-dimensional finite element models were used for the purpose of comparison. Cleavage fracture was initiated
by high plastic strains in the vicinity of notch tip. Strains calculated by threedimensional modeling were higher up to 80% than for two-dimensional model. Calculated local cleavage fracture stresses rendered effective surface energy
values of 49J/m2 and 60J/m2, for two-dimensional and three-dimensional numerical model, respectively. Both results are in good agreement with previously published data for medium carbon microalloyed steels.
