Strength Evolution of Geomaterials in the Octahedral Plane under Nonisothermal and Unsaturated Conditions

Current geomechanical applications imply nonisothermal processes of unsaturated geomaterials, in most cases following stress paths different from the classical triaxial compression often used in laboratory testing. Although the effects of temperature, suction, and stress-path direction (Lode’s angle) on the strength of geomaterials have been investigated independently, an integrated analysis combining the three effects has not yet been...
