Abstract

T*ε-integral values associated with stable crack growth in thin 2024-T3 aluminum single edge notched (SEN) and central notched (CN) specimens were computed directly from the crack tip displacement field obtained by moire interferometry. These results agreed with the T*ε obtained from an elastic-plastic finite element (FE) simulation of the stable crack growth in a SEN specimen. These T*ε variations with stable crack growth also agreed with those determined experimentally in the CN specimens thus suggesting that for a given Γε, T*ε can be used as a stable crack growth and a ductile fracture criteria.
