Fatigue damage evaluation of 316LN stainless steel using acoustic emission monitoring
工程科学学报, 2018 The initiation and growth of fatigue cracks usually lead to serious fatigue failure of steel structures such as pressure vessels and pipelines. Therefore, for the safety and reliability of engineering structures, monitoring the fatigue crack growth and ...

High-cycle fatigue fracture of structural materials under elastic-plastic deformation [PDF]
, 2006 The developed method of recording current values of crack tip opening displacement made it possible to reliably establish the instant when the “material” contact between the borders of a fatigue crack near its tip in a tension half-cycle ceases and the ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1988 The fatigue life of plain carbon steel with residual stress was studied with special reference to the initiation and the propagation of surface fatigue cracks. Tensile residual stresses have no significant influence on crack initiation lives, but increased the fatigue crack propagation rate for surface fatigue cracks.
