Abstract

Effort to describe effect of variable amplitude loading character on fatigue damage cumulation is committed for a metal material of a structural part. It is proposed to quantify the influence of loading character on durability life via damage model incorporating the nonstationarity factor and the spectrum fullness factor. Experimental evidence and analytical results of the proposed model are correlated.
Keywords: variable loading spectrum, damage model, loading fullness factor for spectrum
