Implication

Experimental study demonstrates high fatigue scatter in low carbon manganese steel, suggesting improved reliability assessment through continuum damage modeling.

Key Points

To establish and validate a rapid failure probability prediction method that evaluates fatigue life dispersion in the very high cycle fatigue regime.
Conducted ultrasonic fatigue tests evaluating simple very high cycle fatigue (VHCF) and cumulative fatigue (low cycle fatigue combined with VHCF) in low carbon manganese steel.
Extended a continuum damage mechanics model to the VHCF domain to estimate remaining component fatigue life.
Applied a multiscale framework coupled with fatigue dissipation analysis to rapidly predict failure probability distributions.
Wöhler diagram data revealed substantial scatter in fatigue life within the very high cycle fatigue regime.
The extended continuum damage mechanics and dissipation-based multiscale models successfully characterized the high dispersion of fatigue life for low carbon manganese steel.
