“…The variation of peak stress ratio with confining stress for cemented sands is nonlinear i.e., peak stress ratio increases with decreasing rate Overton, 1989, Chang andKabir, 1994) and many researchers proposed non-linear strength envelope models for both cemented and uncemented soils and also jointed and intact rocks (Mogi, 1966, Barton 1976, Hoek and Brown, 1980, 1988, Barton, 2016, Wu et al, 2017, Tian et al, 2018, Shen et al, 2018. It has been shown in the literature that the classical Mohr-Coulomb failure criterion does not fit well with the failure envelopes of cemented sands which are in general non-linear in shape.…”

The shearing behaviour of reproduced flat LBS grains artificially bonded with ordinary Portland cement (OPC) and Plaster of Paris (PP) was examined using micromechanical experiments.Monotonic shearing tests showed a distinct variation in the load-displacement relationship at low, medium and high normal loads and a non-linear shear strength envelope was proposed. For OPC bonded sand grains, a brittle-ductile transition at 20-30 N normal load was observed and three breakage mechanisms in shearing (chipping, shear cracks, and crushing) were distinguished in accordance with the changes in the load-displacement curves. OPC bonded sands showed a predominant dilation at lower normal loads, whereas PP bonded sands were highly compressive. Based on previously published works using element-scale tests, a new mechanism for dilation under micromechanical testing was proposed in the study. Cyclic shearing tests were conducted on OPC bonded sands and the effects of increased displacement amplitude and normal load were highlighted.

“…Based on the comparisons of the CM in Figure 9a and the TM in Figure 10a, it can be found that the predicted values of the concrete failure strength with the Lubliner-Ottosen SC are almost equivalent to those with the Ottosen SC under a low confining pressure and slightly higher than those under a higher confining pressure, but the predicted concrete failure strength values are far lower than those with the Lubliner-Oller SC and higher than those with the Lubliner-Lee SC under a high hydrostatic pressure. Under the condition of tension-dominated stress states, all these failure criteria achieve the same precision, but the Lubliner-Lee SC deviates from the other SCs with Except for the H-H-T and W-W-5 SCs, other concrete failure criteria, including the Podgorski SC, 70 Kotsovos SC, 71 Guo-Wang SC, 72 Song-Zhao SC, 73 and even the NUSC 74 and GNSC, 75 are further investigated and surveyed.

The Lubliner strength criterion (SC) can achieve desirable responses in the tension‐dominated and plane compressive stress states but overestimates the concrete strength under triaxial compression. Moreover, additional breakpoints without continuous derivatives occur along the hydrostatic pressure axis. The primary causes for these problems include the Lubliner SC constant γ parameter and breakpoints along the piecewise linear meridians. Therefore, a new Lubliner–Ottosen SC is developed with the parameter γ determined based on the Ottosen SC. The meridian contains smoothly connected straight and curved lines. Moreover, the deviatoric traces of the corresponding failure surface gradually change from curved triangles to approximate circles with increasing hydrostatic pressure. Finally, the proposed Lubliner–Ottosen SC is compared with other failure criteria and experimental results for concrete. Regardless of triaxial or nontriaxial compression, the new criterion can suitably represent the failure behavior of concrete in the various multiaxial stress states.

In this paper, the common failure criteria of existing soil materials, such as the Mohr–Coulomb criterion, Drucker–Prager criterion, Lade–Duncan criterion, Matsuoka–Nakai criterion andAC-SMP criterion are systematically discussed, and the applicability of these criteria is quantitatively analyzed through the true triaxial test results of loess, so as to provide reference for the accurate selection of specific criteria in engineering practice. The failure criteria are classified from several aspects, such as whether the influence of the intermediate principal stress and the change of spatial moving plane are considered, analyzed and discussed, respectively. According to the true triaxial test results of undisturbed loess, the difference of strength criterion between the three-dimensional failure plane and p-q plane is analyzed, and based on the true triaxial test data of undisturbed loess, the error analysis of each failure criterion is carried out. The results show that the AC-SMP criterion is in good agreement with the test results, and can accurately evaluate the true triaxial test of loess. For different soil materials or different stress states, it is necessary to select appropriate failure criteria. This study shows how to choose the corresponding failure criterion under specific circumstances, so as to better satisfy the theory and practice and provide reference for engineering.
