Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Microstructure-sensitive computational multiaxial fatigue of Al 7075-T6 and duplex Ti-6Al-4V
Multiaxial fatigue experiments are expensive and typically require specialized equipment and specimens, but they are essential to support fatigue design of components that experience multiaxial stress states.

This paper presents the concept of applying life-dependent material parameters to several multiaxial fatigue criteria. This concept reflects the transformation of damage mechanisms in relation to the applied load level, and also in relation to the ...

A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...

Predicting damage to materials under multiaxial fatigue is a complex challenge, especially when normal and shear stresses interact in dynamic and non-linear ways. Traditional methods often oversimplify these interactions, leading to less reliable fatigue

A NEW MULTIAXIAL FATIGUE LIFE PREDICTION MODEL AND ITS APPLICATION (MT)
When mechanical components are subjected to multiaxial cyclic loading during operation, the additional strengthening effect is easy to occur. Using uniaxial fatigue life calculation formula to predict their life will produce large errors.

Combinations of geometric discontinuities and multiaxial loads appear commonly in engineering components, which raise both stress gradient and multiaxial stress states near the notch root.
