Sažetak
Fracture behavior of two types of steel (1.4762 and 1.7147) is compared based on their numerically obtained J-integral values. J-integral was chosen to quantify crack driving force using finite element (FE) stress analysis applied to single-edge notched bend (SENB) and compact tensile (CT) type fracture specimen. Resulting J-values are plotted for growing crack length (Δa – crack length extension) at different a/W ratios (a/W – relative crack length ; 0.25, 0.5, 0.75). Slightly higher resulting values of J-integral for 1.4762 than 1.7147 can be noticed. Also, higher a/W ratios correspond to lower J-integral values of materials and vice versa. J-integral values obtained by using FE model of CT specimen give somewhat conservative results when compared with ones obtained by FE model of SENB specimen.
