“…Nevertheless, most experimental techniques for measuring the strains provide information only from the external surface. Experimental systems such as strain gauge, extensometer, replica technique, digital image correlation, Moiré interferometry, or electronic speckle pattern interferometry can be used for measuring the strain at certain spot or across an area. Information from the interior of the material can only be measured experimentally in most engineering materials via synchrotron X‐ray diffraction, although access to such facilities is extremely limited .…”

In this work, the multiaxial behaviour of 316 stainless steel is studied under the lens of critical plane approach. A series of experiments were developed on dog bone–shaped hollow cylindrical specimens made of type 316 stainless steel. Five different loading conditions were assessed with (a) only tensile axial stress, (b) only hoop stress, (c) combination of axial and hoop stresses with square shape, (d) combination of tensile axial and hoop stresses with L shape, and (e) combination of compressive axial and hoop stresses with L shape. The fatigue analysis is performed with four different critical plane theories, namely, Wang‐Brown, Fatemi‐Socie, Liu I, and Liu II. The efficiency of all four theories is studied in terms of the accuracy of their life predictions and crack failure plane angle. The best fatigue life predictions were obtained with Liu II model, and the best predictions of the failure plane were obtained with Liu I model.

“…Experimental investigations in last years have provided numerous hypotheses on the Multiaxial High-Cycle Fatigue criteria. In literature, many proposals of such criteria can be found [20][21][22][23][24][25][26][27][28]. From a numerical point of view, the criteria which may be conveniently applied are of two types: criteria based on stress state invariants and criteria using average stresses or deformations in an elementary volume.…”

A fatigue test on a full scale panel with complex loading condition and geometry configuration has been carried out using a triaxial test machine. The demonstrator is made up of two skins which are linked by a transversal butt-joint, parallel to the stringer direction. A fatigue load was applied in the direction normal to the longitudinal joint, while a constant load was applied in the longitudinal joint direction. The test panel was instrumented with strain gages and previously quasi-static tests were conducted to ensure a proper load transferring to the panel. In order to support the tests, geometric nonlinear shell finite element analyses were conducted to predict strain and stress distributions. The demonstrator broke up after about 177000 cycles. Subsequently, a finite element analysis (FEA) was carried out in order to correlate failure events; due to the biaxial nature of the fatigue loads, Sines criterion was used. The analysis was performed taking into account the different materials by which the panel is composed. The numerical results show a good correlation with experimental data, successfully predicting failure locations on the panel.

“…The SWT model encountered the influence of mean stress on damage assessment within low-cycle and high-cycle fatigue domains by means of maximum cyclic stress. [2][3][4][5][6][7] Due to simplicity of the SWT model, its applicability to assess fatigue damage for notched and un-notched specimens [8][9][10][11] has been promoted over last few decades. In these studies, damage assessment based on the SWT has noticeably overpredicted life data in materials undergoing various loading spectra.…”

Fatigue damage and life of SS304, S45C, and SNCM630 steel samples tested at various irregular axial‐torsional loading spectra were evaluated by means of 7 Smith‐Watson‐Topper (SWT) type damage descriptions. The overall damage was calculated over peak‐valley events of counted cycles by means of the product of stress and strain corresponding to the areas within stress‐strain hysteresis loops. Fatigue lives of 304 steel samples predicted by the SWT, Lorenzo‐Laird, Szolwinski‐Farris, and Chen‐Xu‐Huang models were found noticeably larger than those of experimentally obtained at various loading spectra. Predicted lives by these descriptions were found moderately in agreement with experimental data of S45C and SNCM630 steel samples. The predicted lives of steel samples by Socie, Lv et al, and the one presented in this study were closely agreed with experimental data due to their different descriptions. The modified SWT model further included the product of maximum shear stress and shear strain amplitude and related the overall damage to fatigue life through Coffin‐Manson equation. The choice of model descriptions for damage assessment was discussed based on their terms, areas underneath of hysteresis loops, and material damage mechanism.
