Towards a Generalized Bounding Surface Model for Cohesive Soils
Since its inception over thirty years ago, the bounding surface model for cohesive soils has been progressively improved and expanded to a three-invariant, elastoplastic formulation that accounts for the initial and stress-induced anisotropy. More recently, a simplified version of the model served as the basis for a simplified form of the anisotropic model. In order to more accurately simulate the softening of natural clays, the associative flow rule used exclusively in all earlier versions of the model was recently extended to include a non-associative flow rule. In an effort to unify the aforementioned versions of the bounding surface model for cohesive soils, a generalized model framework has been developed. The present paper describes this framework.
