“…When a multiaxial stress/strain state is needed to be considered, it is usually reduced to an equivalent uniaxial one for multiaxial fatigue assessments . The established criteria for multiaxial fatigue evaluation can be categorized as the effective stress/strain approach, the energy‐based approach, and the critical plane approach . The critical plane approach is developed based on the initiation and accumulation of fatigue damage on a certain critical plane and considers that the cumulative fatigue damage occurs on the certain critical plane .…”

This paper presents analytical and experimental investigations for fatigue lives of structures under uniaxial, torsional, multiaxial proportional, and non‐proportional loading conditions. It is known that the rotation of principal stress/strain axes and material additional hardening due to non‐proportionality of cycle loading are the 2 main causes resulting in shorter fatigue lives compared with those under proportional loading. This paper treats these 2 causes as independent factors influencing multiaxial fatigue damage and proposes a new non‐proportional influencing parameter to consider their combined effects on the fatigue lives of structures. A critical plane model for multiaxial fatigue lives prediction is also proposed by using the proposed non‐proportional influencing factor to modify the Fatemi‐Socie model. The comparison between experiment results and theoretical evaluation shows that the proposed model can effectively predict the fatigue life due to multiaxial non‐proportional loading.

“…) that the direction of crack initiation plane changes in tension–torsion tests, depending on the ratio between torsional and axial strains. To predict the direction of crack initiation plane, several researchers have proposed different methods that can be divided, according to the considered parameters, into principal stress‐based/strain‐based methods, shear stress‐based/strain‐based methods and cumulative damage methods …”

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.

“…The first phase is generally explained by a rapid change in the dislocation density inherited from the quench treatment, the second is related to the formation of dislocation sub-structure and carbide coarsening under the action of time, temperature and cyclic load, while the third phase is a consequence of micro-damage development in the material that ultimately causes failure of the tested sample (cf. Seweryn et al 2008;Szusta and Seweryn, 2010).…”

Thermomechanical low cycle fatigue behaviour of P91 steel used in power industry applications has been extensively investigated. The constitutive model of Armstrong-Frederick, extended with temperature rate effects, has been applied to describe the behaviour of the thermo-elastic-plastic material. The proposed model has been successfully implemented in simulation of low cycle fatigue of the examined steel in two different temperatures.
