A generalized nonlinear three-dimensional failure criterion based on fracture mechanics
Journal of Rock Mechanics and Geotechnical Engineering, 2023 Based on fracture mechanics theory and wing crack model, a three-dimensional strength criterion for hard rock was developed in detail in this paper. Although the basic expression is derived from initiation and propagation of a single crack, it can be ...

Soils and Foundations, 1998 ABSTRACT Undrained monotonic loading triaxial compression and extension tests were conducted on Toyoura sand. It was found that the shear behavior was more contractive and softer in triaxial extension than in triaxial compression. This difference suggests that the stress conditions, such as the direction of the principal stress and the magnitude of ...
