Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings [PDF]
, 2013 Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior importance for the applicability of

Prediction of Fatigue Crack Initiation under Variable Amplitude Loading: Literature Review
Metals, 2023 Metallic materials are widely employed in engineering constructions, and one of the most common failure mechanisms in metals is fatigue failure. Even though metal fatigue has been studied for almost 160 years, many problems remain unsolved.

On the applicability of Miner’s rule for multiaxial fatigue life calculations under non-proportional load histories [PDF]
Fracture and Structural Integrity, 2017 Fatigue design routines and computer codes must use some damage accumulation rule to deal with variable amplitude loadings (VAL), usually Palmgren-Miner (or Miner’s) linear rule for lack of a clearly better option.

The Strain energy density to estimate lifetime of notched components subjected to variable amplitude fatigue loading [PDF]
Fracture and Structural Integrity, 2019 In the present paper, the approach based on the strain energy density (SED) averaged over a structural volume is reformulated to estimate the lifetime of notched components subjected to variable amplitude (VA) uniaxial fatigue loading.

Retardation effects due to overloads in aluminium-alloy aeronautical components [PDF]
, 2017 Fatigue data are generally derived under constant-amplitude loading conditions, but aircraft components are subjected to variable-amplitude loading. Without interaction effects, caused by overloads and underloads intermingled in a loading sequence, it ...

A comparison of fatigue lifetime prediction models applied to variable amplitude loading [PDF]
, 2017 The loads imposed on e.g. offshore structures can vary considerably with time. Lifetime prediction methodologies need to consider possible acceleration and retardation of the crack growth rate due to load sequences.
