Sažetak
Numerical fracture toughness assessment of two types of steel, AISI 420 and AISI 431, has been conducted in this paper. The J-integral is chosen as a criterion for fracture behaviour comparison of compact type (CT) specimens made of investigated materials. The values of J-integral are determined through a newly developed algorithm using finite element (FE) stress analysis results of numerically simulated single specimen test method, which is usually employed for experimental J-integral assessment. J-integral values are presented in dependence on specimen crack growth size (Δa) for three initial measures of specimen's crack size, a/W = 0.25, 0.5, 0.75.
