Prediction of the T0 Shift between Specimens of Different Constraints Using the T-Stress Based T-Functions

This work applies the T-stress based T-functions to predict the T 0 shift between types of specimens exhibiting different in-plane constraint levels at cleavage fracture. The analytical model predicts accurately the shift of T 0 values estimated using fracture toughness data measured with deep-notch SE(B) specimens and C(T) specimens, and the shift of T 0 values from deep and shallow cracked SE(B) specimens.
