Originální abstrakt

Fracture of cylindrical specimens with longitudinal surface notch under compression test were experimentally studied. Geometry of the specimens (height to diameter ratio, notch depth) and frictional conditions (grooved, dry smooth and lubricated smooth platens) were changed. Subsequent finite element numerical simulation of the tests produced local stress-strain history at the notch tip. This was used for evaluation of the ability of various ductile facture criteria to predict correctly the fracture initiation. Results for individual criteria are presented and discussed in the paper.
