An extended super/subloading surface model for soft rock considering structure degradation. [PDF]
PLoS One, 2021 The strain-softening and dilatancy behavior of soft rock is affected by the loading history and the development of structure. This study regards soft rock as a structured and overconsolidated soil and develops a new elastoplastic model based on the ...

Application of a Stress-Fractional Model for Capturing the Stress-Strain Behavior of Granular Soils
Advances in Civil Engineering, 2021 Granular soils usually serve as the filler material in geotechnical engineering. This study presents the development and application of a stress-fractional model for granular soils with different initial material states.

Modified unified critical state model for soils considering over-consolidation and cyclic loading behaviours. [PDF]
Sci Rep, 2023 This paper presents a modified unified critical state model to predict the mechanical responses of both clays and sands under over-consolidation and cyclic loading conditions on the basis of clay and sand model (CASM), which is named as CASM-kII. Through

An EVP Double‐Yield Nonstationary Flow Surface Model for Soft Clay
Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022 According to experimental findings, soft clay has compression and shear creep. The goal of the study is to develop an elastic‐viscoplastic (EVP) model for the viscous behavior of soft clay. The new EVP model is deduced from the associated flow rule, Yin’s double‐yield surface theory, and the critical state soil mechanics. The nonstationary flow surface

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 45, Issue 16, Page 2321-2370, November 2021., 2021 Abstract This study is aimed at developing an anisotropic elastoplastic constitutive model for geomaterials at finite strain and its stress calculation algorithm based on the fully implicit return‐mapping scheme. The Cam‐clay plasticity model is adopted as a specific prototype model of geomaterials.
