Sažetak:
: Numerical calculation of J-integral on BxB fracture toughness specimens with thickness of B=36 mm has been performed. For this thickness neither pure plane stress nor pure plane strain state assumption is not valid, because there prevails mixed state-of-stress. In that case, only solid finite element model of the specimen give us satisfied results. This paper shows that finite element solutions of J-integral for planes extracted from the 3-D model enable us nearest results to the experimental ones. However, it seems that for the structures with medium thickness plane strain state is more dominating, especially after initiation of the crack.
