| The presented article focused on the issue of cracking in forgings obtained through metal forming processes. In metallic materials, ductile and brittle cracking can be distinguished. Due to the nature of the article, attention was focused on the criteria for ductile fracture. Experimental tests and numerical analyses have enabled the definition of damage function values for cylindrical specimens made of S355 steel in a rotational compression test within a channel under cold forming conditions, in accordance with nine currently used plastic fracture criteria. The paper also implemented the determination of the damage function value based on the Pater hybrid criterion. Numerical analyses were conducted in the Simufact. Forming v.15 software. During the tests, the distribution of stresses and strains was analysed, which enabled for the determination of stress triaxiality and critical values of the damage function for all examined ductile fracture criteria. The tests showed that the hybrid Pater fracture criterion and the other criteria analysed accurately predict the location of the fracture in the tested specimens in the rotational compression test conducted under cold working conditions. |
