dc.description.abstractFrom the production point of view, the appearance of cracks of metal components is very negative, except in some metal forming processes when fracture is deemed necessary in order to obtain a product with the required characteristics. However, in general a plastic crack stops further forming processes and is thus a major factor limiting the increase of productivity, especially in cold metal forming. Previous studies have confirmed that the mechanism of nucleation, growth and coalescence of microcavities, which control the level of microstructure damage and lead to initiation and expansion of fracture, are influenced by various factors, with the generated stress state in the forming zone having the strongest influence. In this paper, these problems were investigated in the process of upsetting of cylindrical sample with flat plates. Based on the SEM examination of the microstructure of C45E steel with the aim to quantify microstructural damage and the FEM analysis of the stress state in the critical zone of forming, it can be concluded that there is a different impact of individual components of stress on the accumulation of critical level of damage.
