Sažetak
Fracture behaviour of two steels, AISI 420 and ASTM A618, was numerically investigated using a newly developed algorithm for the J-integral calculation. The algorithm is based on the results of the finite element (FE) simulation of single specimen test method, commonly used in experimental determination of J-integral. FE stress analysis results are used as an input for the algorithm which calculates J values on three different paths around the crack tip, taking their average value as final. The obtained J-integral values are plotted against specimen crack growth steps (Δa). In that way, valuable measures of J-integral acting as a crack driving force are available. Research was done using a FE model of compact type (CT) specimen with three initial crack lengths, a/W = 0.25, 0.5, 0.75.
