Validation of multiaxial stress-based analysis on specimens from ČSN 41 1523

Popis výsledku v původním jazyce

The paper describes the study on fatigue strength prediction criteria within the scope of a common high-cycle fatigue strength analysis including the effect of multiaxial loading. The study is based on own experiments performed on tubular specimens from ČSN 41 1523 structural steel in a combination of various load channels: push-pull, torsion, pressurizing, bending. The prediction methods are assessed in various fatigue lifetimes ranging from 100 000 cycles to 750 000 cycles. No substantial deviation of the methods behaviour in various lifetimes is observed, likely due to the stresses being low enough not to induce substantial plasticity effects. The PCRN method and the Liu-Zenner methods result in best predictions. Results of the recently proposed MMP method allowing the users to evaluate quickly multiaxial load states remain promising and only slightly worse than these two best methods.
