Abstract: Toughness scaling model arising from basic definition of Dodds and Anderson has been applied for data adjustment in constraint dependent regime in transition region and data from subsized pre-cracked specimens. Similar model has been developed based on local parameters - Weibull stress and location parameter. The fracture toughness temperature diagram has been predicted by using data from the pre-cracked Charpy type specimen corrected applying the toughness scaling model. Introducing the statistical scale effects corrections good correlation of predicted data to those measured with 1T specimens has been obtained.
