Abstract
This work applies the T-stress based T-functions to predict the T-o Shift b etween types of specimens exhibiting different in-plane constraint levels a t cleavage fracture. The analytical model predicts accurately the shift of T-o values estimated using fracture toughness data measured with deep-notch SE(B) specimens and C(T) specimens, and the shift of T-o values from deep and shallow cracked SE(B) specimens.
