Cumulative fatigue damage theories for metals: review and prospects

International Journal of Structural Integrity, 2023
PurposeScholars mainly propose and establish theoretical models of cumulative fatigue damage for their research fields. This review aims to select the applicable model from many fatigue damage models according to the actual situation. However, relatively

Effects of pre-fatigue damage on mechanical properties of Q690 high-strength steel

Construction and Building Materials, 2020
This paper investigates the residual strength of Q690 high-strength steel previously damaged by fatigue. Pre-fatigue damage was induced by subjecting the specimens to nine different loading cycles without causing fracturing under three initial cyclic ...

Vehicle-induced fatigue damage prognosis of orthotropic steel decks of cable-stayed bridges

Engineering structures, 2020
Orthotropic steel deck (OSD) in a long-span cable-stayed bridge is vulnerable to fatigue damage at the deck-to-rib (DTR) joints due to excessive vehicle-induced dynamic stresses.
