It is an essentially open question as to how well characterizations of through-thickness crack growth based on parameters such as J, crack-tip opening displacement, and tearing modulus describe ductile cracking in important structural configurations such as the part-through surface-cracked plate.

The new method of surface crack growth calculation under linear elastic fracture mechanics (LEFM) conditions facilitates the use of stress-intensity factor K (and in particular its ?K range) as a tool to estimate the fatigue life of cracked plates under tensile loads. This is made possible by determining a set of parameters in order to obtain equal ?K values and analogous crack propagation rates in two widely different specimen geometries, a plate and a standard compact type (C(T)) specimen. A comparison of fatigue lives with equivalent crack growth for both types of specimen suggests that in using the proposed procedure, the significance of ?K values in a part-through crack is closely related to that of a through crack in a C(T) specimen.

Within the last decade there has been an increasing awareness that use of standards deeply notched fracture mechanics test specimens can result in substantial over-or-under-assessments of the real fracture toughness associated with shallow surface cracks.

Surface crack growth in plates made of aluminum 7050 alloy is studied by the Rubber Impression Method (RIM). RIM is an experimental technique used to estimate the three-dimensional crack profiles by inserting and taking out gel-state rubber from the crack opening during the test. Far field tensile loading was applied to the surface-cracked thin plates with various crack geometries. Three stages of fracture are found; (1) flat stable tearing close or up to through thickness (2) unstable lateral tearing with flat tunneling transitioning to slant fracture and (3) unstable fully slant fracture. Crack profiles measured by the RIM were compared with the crack extension marked by fatigue loads. Generally, reasonable agreement is obtained except the region adjacent to the free surface. The Crack Tip Opening Displacement (CTOD) at the center of the crack was obtained by examining the crack opening profiles at different load levels. The results indicate that the shallow cracked specimen has relatively high value of CTOD at the initiation of stable crack growth. Due to complex geometry of the three-dimensional crack the RIM showed its limits in precise measurement of the crack tip details. Nevertheless the RIM could be an effective way to study the overall behavior of ductile crack growth.
