An engineering approach to assess constraint effects on cleavage fracture toughness

This study presents a simplified approach to parameterize constraint effects on the fracture toughness of ferritic steels in the ductile-to-brittle transition (DBT) region under plane strain, small-scale yielding conditions for non-zero T-stress. The Weibull stress serves to couple near tip and glob...
