Fatigue Strength Under Spectrum Loading
AI summary Read the abstract
This paper examines fatigue strength of metals under variable-amplitude loading, noting that rare high-stress events can cause localized microplastic straining — a materials science term referring to microscopic deformation in metal crystals, unrelated to environmental plastic pollution. This paper is not relevant to microplastic pollution or human health from synthetic polymer contamination.
In-service loading often is characterized by random variable amplitudescyclic loads random variable amplitudes which cannot be represented by sinusoidal type of loading sufficiently. Rare events may introduce microplastic strainingfatigue microplastic straining and...
