“…Due to this limitation of current design procedures, critical plane (CP) models 4–27 have gained popularity as they have been demonstrated to produce satisfactory assessments for certain set of materials/loading conditions, and more importantly, they represent fatigue damage in a more phenomenological way. Hence, current literature is equipped with very large numbers of such CP models 4–56 . In general, these models have been validated for limited class of materials and loading conditions.…”

The present study validates recent as well as extensively used critical plane (CP)‐based fatigue life assessment models for 10 ferrous and 7 non‐ferrous materials. Fourteen CP models, including recently reported in‐house developed model, have been analyzed. These models use resolved stresses, strains, strain energy density, and combinations of stresses and strains to identify critical plane and quantify fatigue damage. The loading conditions cover various proportional and non‐proportional axial‐torsion strain paths with different phase shift angles with (or without) mean stress/strain component(s), loading waveforms, and asynchronous axial‐torsion stain paths. The comparative study brought out the goodness of various models by quantifying the extent of scatter and computational time. Some of the strain energy density‐based models (including in‐house model) have been shortlisted, which produced accurate fatigue life assessments. Among the shortlisted models, in‐house model is free from the calculation subjectivities of resultant shear and performs faster fatigue damage calculations.

“…Based on these observations, it can be concluded that the material parameters assessing the effect of shear and normal stress on fatigue life are not constant, but instead dependent on life. The phenomenon of the life dependency of the material parameters in multiaxial fatigue models has been analysed in [21,[37][38][39][40][41]. It was demonstrated that the life-dependent material parameters can be successfully applied to multiaxial stress-and strain-based fatigue life prediction models under cyclic proportional and non-proportional loading paths with zero mean stress.…”

This study presents the life-dependent material parameters concept as applied to several well-known fatigue models for the purpose of life prediction under multiaxial and non-zero mean loading. The necessity of replacing the fixed material parameters with life-dependent parameters is demonstrated. The aim of the research here is verification of the life-dependent material parameters concept when applied to multiaxial fatigue loading with non-zero mean stress. The verification is performed with new experimental fatigue test results on a 7075-T651 aluminium alloy and S355 steel subjected to multiaxial cyclic bending and torsion loading under stress ratios equal to R = −0.5 and 0.0, respectively. The received results exhibit the significant effect of the non-zero mean value of shear stress on the fatigue life of S355 steel. The prediction of fatigue life was improved when using the life-dependent material parameters compared to the fixed material parameters.

“…The prediction quality of multiaxial fatigue strength criteria is often assessed on experiments with various load combinations of push–pull and torsion [ 1 , 2 , 3 , 4 ]. By some experiments, axial loading of specimens can be induced by bending, which causes non-constant stress distribution over the cross-section [ 5 , 6 , 7 , 8 , 9 ]. Relatively rarely, the inner pressure is applied on hollow specimens [ 10 , 11 , 12 ].…”

Validation of Multiaxial Fatigue Strength Criteria on Specimens from Structural Steel in the High-Cycle Fatigue Region

et al. 2020

The paper describes results of fatigue strength estimates by selected multiaxial fatigue strength criteria in the region of high-cycle fatigue, and compares them with own experimental results obtained on hollow specimens made from ČSN 41 1523 structural steel. The specimens were loaded by various combinations of load channels comprising push–pull, torsion, bending and inner and outer pressures. The prediction methods were validated on fatigue strengths at seven different numbers of cycles spanning from 100,000 to 10,000,000 cycles. No substantial deviation of results based on the selected lifetime was observed. The PCRN method and the QCP method provide best results compared with other assessed methods. The results of the MMP criterion that allows users to evaluate the multiaxial fatigue loading quickly are also of interest because the method provides results only slightly worse than the two best performing solutions.
