Application of the Concept to Fatigue Crack Growth in Large-Scale Yielding
SourceFatigue crack propagation tests were performed on compact tension specimens of AISI 316 steel, in the elastic-plastic and plastic regions. The parameter ΔJ was chosen to characterize propagation. Results show that there is a Paris law type correlation between propagation rate and ΔJ. An effect on propagation rate, which is attributed to the R = Pmin/Pmax ratio, has been noted.
A numerical verification of the applicability of the ΔJ concept was determined by use of a theoretical equation. These results were compared with experimental results.
