“…It will be wider (broadened peak) for non‐Masing behavior due to the introduction of additional yield levels 114 . The main advantage of this approach is that it does not contain any parameter to be fitted, and the PDF can be calculated directly from an experimentally obtained stress–strain hysteresis loop as follows 109,114 :

f ((), σ_{italicyt}) goodbreak= goodbreak- \frac{2}{E^{2}} ((), \frac{d^{2} Δ σ}{d Δ ε^{2}})

Over the last 50 years, many researchers have contributed significantly towards understanding the Masing/non-Masing behavior of materials. However, there has been no review article or scientific report published to date that highlights the progress made in this domain. This article presents a state-ofthe-art comprehensive review and analysis of the Masing/non-Masing behavior of materials under low cycle fatigue loading. Understanding of Masing/ non-Masing behavior is important for the development of fatigue-resistant materials, prediction of fatigue life, and constitutive modeling and simulation. The influence of various factors such as stacking fault energy, temperature, strain amplitude, and loading conditions on Masing/non-Masing behavior has been summarized in this article. The literature pertaining to the internal microstructural changes observed in different materials by various researchers has been collected and compiled. The different methods of analyzing Masing/ non-Masing behavior reported in the open literature are assessed and presented. The importance/significance of Masing/non-Masing behavior in constitutive modeling and fatigue life prediction has also been highlighted. Finally, conclusions based on the review and the potential problems required to be resolved in the future are also pointed out.

“…There is ample evidence in the literature, described in the following text, that the fatigue behavior of hollow or tubular specimens is reduced relative to that of solid, cylindrical specimens. A lower number of cycles to failure of hollow/tubular specimens (relative to solid, cylindrical) in multiple studies on alloys ranging from structural steels [27][28][29] to stainless steel [30,31] to Alloy 800 [30] to an aluminum alloy [32]. There was an exception observed for a stainless steel specimen with a 4 mm thick wall at a lower strain range [31].…”

“…There was an exception observed for a stainless steel specimen with a 4 mm thick wall at a lower strain range [31]. Further, this fatigue life detriment was observed to increases with decreasing specimen wall thickness [29], attributed to crack growth rates decreasing with increase in wall thickness [29] due to differences in internal plastic strain [31]. To the authors' knowledge, the influence of tubular specimens on the creep-fatigue (CF) behavior and cycles to failure is not reported.…”

“…The hysteresis behavior of the torsional cycle is comparable to that of the tension–compression cycle [ 1 , 2 , 3 , 4 ]. Furthermore, some materials exhibit non-Masing behavior under torsional cyclic loading [ 5 ]. The investigations reported in references [ 2 , 6 , 7 , 8 ] found that the hysteresis loop of the material under axial load and shear load is different, and the mechanism of crack initiation and propagation is also different.…”

In this paper, torsional fatigue failure of 30CrMnSiNi2A steel which exhibited non-Masing behavior was studied under different constant shear strain amplitudes, using thin-walled tubular specimens. The relationship between shear fatigue and the evolution of meso-deformation inhomogeneity and the prediction method of the torsional fatigue life curve were investigated. Shear fatigue of the material under constant amplitude was researched by numerical simulation with reference to tests, by using crystal plasticity of polycrystalline representative volume element (RVE) as the material model. Considering the non-Masing behavior of material, when determining the parameter values of the crystal plasticity model the correlation between these parameters and strain amplitude was taken into account. The meso-deformation inhomogeneity with increments in the number of cycles was characterized by using the statistical shear strain standard deviation of RVE as the basic parameter. Considering the effect of strain amplitude on fatigue damage, ratio cycle peak stress/yield stress was taken as the weight to measure the torsional fatigue damage and an improved fatigue indicator parameter (FIP) to measure the inhomogeneous deformation of the material was proposed. The torsional fatigue life curve of 30CrMnSiNi2A steel was predicted by the critical value of the FIP and then the result was confirmed.
