Anisotropic Plasticity Model for Undrained Cyclic Behavior of Clays. II: Verification
Publication: Journal of Geotechnical Engineering
Volume 118, Issue 2
Abstract
A constitutive model for the stress‐strain‐pore pressure behavior of saturated cohesive soils under both monotonic and cyclic loadings has been presented in the companion paper. The model has been implemented into a numerical program to facilitate evaluation of the model's predictive capability. Procedures for model parameter determination are given. Numerical simulations are compared with a set of data encompassing a wide range of stress history, consolidation‐stress ratio, and stress path. In addition, both strain‐controlled and stress‐controlled cyclic tests are considered. The comparisons show that the model is capable of capturing the essential features of undrained cyclic behavior of clays, including: (1) Degradation of undrained strength and stiffness; (2) development of transient and residual pore pressure and deformation; (3) influence of initial consolidation stress condition and stress history; and (4) effect of loading path involving rotation of principal stress direction.
