A constitutive model, based on the concept of scaled memory (SM), is presented to describe the undrained behavior of anisotropic clays subjected to generalized loadings. The SM capabilities that were previously established for one-dimensional cyclic responses are extended to six-dimensional monotonic loadings. SM is simpler than multiyield surface plasticity, and just as capable in modeling anisotropic behavior. The performance of the SM model is illustrated by simulating the stress-strain responses of K0 -consolidated clays during combined triaxial-torsional tests.
