Transitional Yielding Model for Clay

Abstract

An approach is presented for analytical modeling of the full range of material behavior of normally consolidated to heavily overconsolidated clays. The approach has the capability of describing both drained and undrained, path dependent inviscid response under static and cyclic loads. The modified Cam‐clay form of the yield surface is allowed to expand or contract depending on the loading history. Numerical experiments and comparisons with experimental results show that various load‐deformation responses including strain hardening, strain softening, dilation, and hysteresis effects can be modeled.
