“…Although these methods are usually able to predict multiaxial fatigue damage in in-phase loading conditions, they are not precise enough to study multiaxial fatigue damage in out-of-phase loading conditions. The reason is that in multiaxial fatigue damage, there are some parameters, such as mean stress, [3][4][5][6] stress ratio, 7-9 material properties, 10,11 phase difference 6,12,13 and temperature, 7 , which can affect fatigue damage.…”

A new method for predicting crack plane direction in high‐cycle multiaxial fatigue is proposed. This method considers material properties and loading conditions. Two situations are considered: (i) in‐phase loading, where the crack plane direction only depends on the loading condition and material properties have little influence on it, and (ii) out‐of‐phase loading, where the crack plane direction is affected by both loading conditions and material properties. The prediction accuracy is assessed by comparison with several experimental results, including different loading conditions and materials. The results show that the proposed method provides a good prediction capability for these experiments.

“…According to this definition, the angle ω is constrained between 0°and 180°. Because of the definition of the angle in the experiments, the calculation of ω in Eqs ( 5) and ( 6) should be modified as Eqs (10) and (11).For in-phase loading:…”

“…At present, there are three major approaches to estimating the multiaxial HCF life, that is, the stress invariant methods, 3,4 mesoscopic scale method, 5,6 and critical plane-based method. [7][8][9][10][11][12][13][14][15] Among these methods, the critical plane-based method is considered as the very effective since the critical plane criterion is based on the physical observation of the fatigue failure.…”

In the present paper, a brief review for some existing critical plane-based life prediction models is presented, and limitations of these models in reflecting the influence of mean stress on fatigue life are discussed. It is found that the effect of mean normal stress on fatigue damage has been well taken into account for most of the critical plane-based fatigue life prediction models, while mean shear stress effect is not well considered in these models. Therefore, a new critical plane-based multiaxial high cycle fatigue life prediction model is proposed in this paper to account for the effects of both mean shear and normal stresses. The shear Walker factor and mean normal stress sensitivity index are introduced in the developed criterion to consider the effects of mean shear and normal stresses, respectively. Procedures to determine the damage parameters acting on the critical plane and to calculate the material constants contained in the proposed model are all presented. Experimental validations by using six different materials show that most of the predictions are within a factor of 3 in fatigue life.

Three categories of models are usually used: critical plane-based models (Carpinteri and Spagnoli, 2001; Carpinteri et al., 2003, 2014b; Papuga and Ruzicka, 2008; Shang et al., 2007; Shang and Wang, 1998; Susmel and Lazzarin, 2002; Zhang and Yao, 2011; Zhang et al., 2018), mesoscopic scale-based models (Brünig et al., 2011; Flaceliere et al., 2007; Eslami et al., 2016; Ju and Ko, 2008; Shariyat, 2010; Tay et al., 2008) and energy-based models (Ahmadzadeh and Varvani-Farahani, 2016; Chen et al., 1999; Zhu et al., 2012, 2017). Since the critical plane method has physical meaning, it is widely used in service.…”

Based on the critical plane determined by the weight function method, two algorithms for multiaxial cycle counting method are proposed by modifying the rainflow and range cycle counting methods. The proposed two algorithms can be applied to multiaxial random loading, and be suitable to any critical plane-based fatigue life prediction models, since the counted cycles or reversals are represented by the start time and end time. The proposed two algorithms are used to predict multiaxial fatigue life by the experimental data of 7075-T651 aluminum alloy, En15R steel and 7050-T7451 aluminum alloy conducted under multiaxial random loading in both high-cycle and low-cycle fatigue region. The life prediction results are in good agreement with the experimental data.
