Herein, the construction of a three-parameter smooth hyperbolic failure criterion for cohesive-frictional materials is presented. The criterion has the form of a hyperbola on the Rendulic plane and of an elliptic hyperboloid with a threefold symmetry in the Haigh–Westergaard principal stress space. The effect of the intermediate principal stress on the strength of the material is taken into account...
To take account of the influence of the intermediate principle stress, Zhang and Zhu [1,2] proposed a three-dimensional (3D) version of the generalized Hoek–Brown strength criterion. The generalized Zhang–Zhu strength criterion is a true 3D version of the Hoek–Brown criterion, not only inheriting the advantages of the Hoek–Brown strength criterion, but predicts the same strength as the two-dimensional...
In this paper, the performance of a hyperbolic failure criterion is compared with the respective performance of five established failure criteria for cohesive-frictional materials. The comparison is both qualitative and quantitative. The data sets used were found in the open literature and refer to five rock types and one concrete. All the data were obtained from true triaxial tests with independent...
