It is 100 years since the well-known Mohr-Coulomb strength theory was established in 1900. A considerable amount of theoretical and experimental research on strength theory of materials under complex stress state was done in the 20th Century. This review article presents a survey of the advances in strength theory �yield criteria, failure criterion, etc � of materials �including metallic materials, rock, soil, concrete, ice, iron, polymers, energetic material, etc� under complex stress, discusses the relationship among various criteria, and gives a method of choosing a reasonable failure criterion for applications in research and engineering. Three series of strength theories, the unified yield criterion, the unified strength theory, and others are summarized. This review article contains 1163 references regarding the strength theories. This review also includes a brief discussion of the computational implementation of the strength theories and multi-axial fatigue. �DOI: 10.1115/1.1472455�

“…In order to separate the effects of volumetric and shear stresses on the volumetric deformation, the pure shear stress path is used in triaxial tests. Triaxial tests with pure shear stress paths make it possible to separate the effect of shear stresses and volumetric stresses on deformations, and have been adopted in recent years to study the mechanical behavior of rocks in the three-dimensional stress space [13][14][15][16][17]. In triaxial tests with pure shear stress paths, the confining pressure is held constant by decreasing the cell pressure increments to one-half of the increment of the axial stresses ðDs 2 ¼ Ds 3 ¼ À0:5Ds 1 Þ.…”

“…Strength is a function of confining stress, strain rate and temperature. Strength tests under different stress states have been carried out by Hunsche and Albrecht [11] in a true triaxial cell. Viscoelasticity and viscoplasticity provide an adequate framework for characterizing the behaviour of rock salt.…”

SUMMARYA constitutive model for crushed salt is presented in this paper. A creep constitutive model is developed first and compared with test results. The constitutive model presented here concentrates on creep deformation because saline media behave basically in a ductile and time-dependent way. An idealized geometry is used as a common framework to obtain stress-strain macroscopic laws based on two deformation mechanisms: fluid-assisted diffusional transfer creep and dislocation creep. The model is able to predict strain rates that compare well with results from laboratory tests under isotropic and oedometric conditions. Macroscopic laws are written using a non-linear viscous approach, which incorporates also a viscoplastic component, based on critical state theory. The viscoplastic term is intended for non-creep deformation mechanisms such as grain reorganization and crushing.
