On the mechanistic difference between in-phase and out-of-phase thermo-mechanical fatigue crack growth
Abstract
The crack driving mechanisms in a coarse grained nickel-base superalloy RR1000 when subjected to in- and out of phase thermo mechanical fatigue are investigated. It is found that the difference in fatigue crack growth rate between these two load conditions is accounted for by the different mechanical conditions at the crack tip region, rather than oxidation effects. This is based on digital image correlation and finite element analyses of the mechanical strain field at the crack tip, which demonstrate that in phase leads to larger crack tip deformation and crack opening. Notably, it is demonstrated that in- and out of phase crack growth rates coincide when correlated to the crack tip opening displacement. ; Funding agencies: European Unions Horizon 2020 research and innovation programme and Joint Undertaking Clean Sky 2 [686600]
