Application of Compliance Techniques for Studying the Effect of Side-Grooving on Stress-Corrosion Crack Kinetics of a High Strength Steel

Abstract

Sub-critical crack growth was estimated from changes in compliance measured during the stress-corrosion cracking of D6AC steel at constant load using 1-T wedge-opening-loading specimens. Agreement of calculated mean crack growth with mean values measured from the fracture surface showed that plastic yielding at the crack tip during loading and subsequent stress-corrosion cracking was negligible. The analysis was then applied to side-grooved specimens where it was demonstrated that, under plane-strain conditions, side-grooving does not significantly affect the stress-corrosion cracking rate in D6AC steel.
