The microstructure and texture effects on fatigue behavior of AZ31B magnesium induced by pre-strain along radial direction

Journal of Materials Research and Technology
In this study, compressional pre-strain was conducted on fatigue samples extracted from the AZ31B rod along the radial direction (RD), leading to the alteration of microstructure and texture, of which the impact on ratcheting behavior and fatigue life ...

Local strain redistribution corrections for a simplified inelastic analysis procedure based on an elastic finite-element analysis [PDF]

Strain redistribution corrections were developed for a simplified inelastic analysis procedure to economically calculate material cyclic response at the critical location of a structure for life prediction proposes. The method was based on the assumption
