Crack propagation under variable amplitude loading [PDF]
Materials Research, 2013 Experience shows that a damage induced by a given cycle is dependent on the loading history. In this regard, the objective of this paper is to study and describe the phenomenology of the loading history on crack propagation. Different loading configuration has been considered for fatigue crack propagation of XC38 steel; overload cycles followed by ...

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

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.

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 ...

Quantitative thermographic method for fatigue life prediction under variable amplitude loading [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2022 AbstractQuantitative thermographic methodology (QTM), which takes energy dissipation as a fatigue indicator, has been successfully applied to predict the fatigue life of materials and welded joints under constant amplitude loading. This study advances the QTM approach for predicting the fatigue life under variable amplitude loading in both low and high

A plain linear rule for fatigue analysis under natural loading considering the sequence effect [PDF]
, 2017 Fatigue under variable amplitude loading is currently assessed with the Palmgren-Miner rule in structural standards, ignoring the order of loading, which would require non-linear or mixed rules, especially for the random loading sequences applied to ...
