Influence of constraint effect ahead of the crack tip on the fracture toughness - computation and experiment
Vlček, Libor ; Chlup, Zdeněk ; Kozák, Vladislav
Aspects of two-parameters fracture mechanics are on the investigation. On the base of 3DFEA the Q parameter and J integral are determined and compared with the experiment.
Application of master curve concept for evaluation of loading rate effects on transition behaviour of steels
Holzmann, Miloslav ; Jurášek, Ladislav ; Dlouhý, Ivo
Various aspects of the master curve methodology have been investigated experimentally based on data obtained with cast manganese steel. Different methodologies of reference temperature determination and the influence of test specimens number have been followed. Transferability of data from small pre-cracked specimens to standard ones has been also followed.
