Metallic materials are extensively used in engineering structures and fatigue failure is one of the most common failure modes of metal structures.Fatigue phenomena occur when a material is subjected to fluctuating stresses and strains,which lead to failure due to damage accumulation.Different methods,including the Palmgren-Miner linear damage rule- (LDR-) based,multiaxial and variable Author Pavaret Preedawiphat,Numpon Mahayotsanun,Keerati Sa-ngoen,Mai Noipitak,Pongsak Tuengsook,SedthaPublish Year 2020Fatigue damage evaluation in A36 steel using nonlinear Jun 01,2012·A36 steel is widely used in the civil infrastructure,such as steel bridges,where fatigue damage can lead to a catastrophic failure.Plastic deformation causes the generation of higher order harmonics in an initially monochromatic Rayleigh wave signal,and this measurable change occurs before macroscopic damage such as cracks appear in a specimen.Characterization of fatigue properties of ASTM A709 high Jun 01,2007·The predicted fatigue life for HPS is more that twice that for A36 steel,indicating the difference in fatigue life is log N = 0.31.This difference is larger than 0.25,the value of standard deviation that has been used to establish a design curve from the mean predicted life.
