“…The plane bending and torsion were generated by a single force applied to lever with a length of 0.2 m. The rotation of specimen by angle β with respect to the lever decomposes the principal moment into bending and torsion moments with a fixed ratio for a given angle β. Details of the applied fatigue stand can be found in [63]. The applied frequency of loading varied between 5 and 30 Hz, depending on the applied stress amplitudes.…”

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 paper describes the experiments aimed at the extension of the method early proposed for the uniaxial fatigue monitoring to the multiaxial modes of loading. The common denominator for both methods approach is based on the possibility of computer‐aided optical analysis of extrusion/intrusion structure, called often surface deformation relief, to be used for quantitative assessment of accumulated fatigue damage and remaining life. Experimental data obtained under the different modes of loading are presented and described as well as some objectives for the future activities are outlined.

This paper presents an approach to the evaluation of the Fatemi‐Socie parameter applied to the lifetime calculation of specimens made of CuZn37 brass. In particular, two factors affecting the calculated fatigue lives are analysed: (i) the influence of stresses calculated by applying the Chaboche plasticity model on the computed lifetime and (ii) the influence of a variability of parameter k of material sensitivity to normal stress on the calculated lifetime. The novelty of the presented research is associated with the fatigue life calculation according to the Fatemi‐Socie model with the introduced k dependence accounting for the lifetime. Underestimation of the calculated stresses results in the higher calculated fatigue lives but with acceptable scatter band. The parameter of material sensitivity to normal stress for the CuZn37 brass varies insignificantly having little impact on the calculated fatigue lives.
