Fracture mechanic safety analyses consist of a comparison between material toughness and toughness requirement of the Investigated structure. For the selection of suitable materials the requirements must be known. The fracture mechanics toughness requirements for a structural component depend on several parameters. Load case, geometry of the component and of a postulated or detected flaw, strength of the steel and the chosen safety criterion are decisive for the toughness requirements. Performing three‐dimensional elastic plastic finite element analyses the toughness requirements for plates of high strength structural steels with surface flaws have been determined as a function of the above mentioned parameters.
