文摘
A linear-accumulative crack growth model is used to assess TMF crack growth. Various load cycle forms also including hold times can be modelled. Crack growth contributions from fatigue, creep and oxidation mechanisms are separated. Model validation against isothermal and TMF crack growth tests on nickel alloy C1023. Easy model application onto components in service.
