Applying the two-parameter fracture mechanics approach to the analysis of failure initiation condition in three-point bend specimens with shallow and deep cracks were tested at various temperatures. Low carbon manganese cast steel was used for the analysis. The effect of crack length on the fracture toughness-temperature diagram has been analysed. Strong dependence of measured fracture toughness on crack tip constraint was observed, no evident differences in fracture morphology were identified except for quantitative ones. The effect of crack tip constraint on brittle fracture characteristics has been quantified by means of the Q-parameter. The role of cleavage fracture stress in brittle fracture initiation under the influence of crack tip constraint has been analysed.
