Hypoplastic Prediction of Path-Dependent Failure in True Triaxial Tests of Granular Soils
Abstract Prediction of failure in soil tests is considered based on hypoplastic modelling of soil behavior and bifurcation analysis. With a comprehensive hypoplastic model for granular soils, a bifurcation condition is formulated for general stress state. The possibility of localized failure in true triaxial tests is investigated by examining the bifurcation condition in element tests following different stress paths. Three situations depending on stress path, including no bifurcation, bifurcation in softening regime and bifurcation in hardening regime, are predicted. Concerning shear localization, the predicted failure surfaces differs significantly in shape from the implemented critical state surface.
