New paper: On the normalization of the undrained stress–strain response of soils
Our paper, co-authored with Prof. Kenichi Soga at UC Berkeley, on the normalization of the undrained stress-strain response of soils has been published in KSCE Journal of Civil Engineering.
Abstract: This paper discusses the influence of the effective confining pressure and normalization parameter on the undrained behavior of soils and explores the conditions necessary for proper normalization within two widely used constitutive soil models: Modified Cam Clay and NorSand. Both models utilize critical state soil mechanics as the theoretical foundation to express the dependency of confining pressure on their behavior. The study emphasizes the significance of normalization parameters, such as the overconsolidation ratio for clays and the state parameter for sands, in predicting behavior across various confining pressures. A key contribution of this work is the explicit statement of the conditions under which both the Modified Cam Clay and NorSand models can be fully normalized.
