Crack growth rate prediction based on damage accumulation functions for creep-fatigue interaction

Andrey Tumanov, V.N. Shlyannikov, A.P. Zakharov

The present study is concerned with formulation of a model for the creep–fatigue crack growth rate prediction on the base of fracture damage zone concepts. It is supposed that crack growth rate can be determined by integration of damage…
