## Description

- description: " A systematic acquisition of fatigue test data was conducted under
    different stress ratio conditions to investigate the effect of mean stress on
    the fatigue properties of carbon/glass hybrid thermoplastic composite rods. Our
    findings revealed that as the stress ratio increased with a higher mean stress,
    the stress pendency of the fatigue life also increased, and the slope of the S-N
    curve became gentler. Under identical stress ratio conditions, hybrid rods with
    a greater volume fraction of carbon fiber exhibited the highest strength and a
    more gradual slope of the S-N curve. To account for mean stress effects, an equivalent
    stress amplitude was introduced, resulting in data collapse at around 107 cycles,
    rendering this approach an industrially useful method to predict fatigue behavior
    when working with limited experimental datasets. This study presents a practical
    technique for estimating fatigue strength under mean stress through a weighted
    average efficiency and equivalent stress amplitude."
