Sažetak
Fracture behaviour of two pressure vessel steels, 20MnMoNi55 and 50CrMo4, was numerically investigated in this work. The research was conducted using numerical models of single-edge notched bend (SENB) and disc compact type (DCT) specimens. J-integral, an important fracture mechanics parameter, was chosen as a criterion for the fracture behaviour comparison of two mentioned steels. J-integral values were determined using newly developed numerical algorithm coupled with finite element (FE) analysis. Numerically obtained J-integral values are presented as a measure of crack driving force versus crack growth size (Δa) for a range of initial crack sizes (a/W = 0.25, 0.375, 0.5, 0.625). Fracture behaviour of two steels was investigated using numerical models of pressure vessels containing also inner axial crack of different sizes (a/t = 0.25, 0.375, 0.5, 0.625). Although Jintegral values cannot be transferred from specimens to real structures, results obtained on pressure vessels have proved useful in engineering assessment of fracture behaviour of such structures.
