Fatigue crack growth of a corner crack at the edge of a hole
Source abstract
Abstract
Abstract The fatigue crack growth (FCG) behavior of a corner crack at the edge of a hole has not been well understood. To address this issue, we first conducted fatigue tests under constant amplitude loading. The results show that the FCG rate along the thickness direction varies nonlinearly with the stress intensity factor range (ΔK) in a log-log scale. This is because the crack-tip stress relaxation at the depth point gets increasingly pronounced as the crack propagates. Finally, we proposed a crack-tip constraint independent FCG rate and the corresponding FCG equation to correlate the crack-tip constraint independent FCG rate with ΔK.
