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 ...

Modified unified critical state model for soils considering over-consolidation and cyclic loading behaviours [PDF]
Scientific Reports, 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

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.

Deformation Behavior of “Shirasu” and its prediction by the Subloading Surface Model
Soils and Foundations, 2002 ABSTRACT The description of the deformation behavior of Shirasu (volcanic sandy soil) by the elastoplastic constitutive equation is studied adopting a subloading surface model with rotational hardening. Also, test results for isotropic consolidation and triaxial compression with several lateral stresses under the drained and the undrained conditions ...

Numerical Analysis of Footing Settlement Problem by Subloading Surface Model
Soils and Foundations, 2009 This article addresses the numerical analysis of the load-settlement relation of footing on a soil ground by the finite difference method incorporating the subloading surface model. The subloading surface model is the elastoplastic constitutive model describing most pertinently the plastic strain rate due to the rate of stress inside the yield surface ...

A subloading surface clay and sand model
, 2022 The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading. These realistic features can be efficiently intro-duced into an existing constitutive model by reformulating it in the framework of subloading surface ...

Viscoplastic deformation analysis for spheroidal graphite cast iron by subloading-overstress model
Nihon Kikai Gakkai ronbunshu, 2020 The time-dependent elastoplastic deformation behavior, i.e. viscoplastic deformation behavior, is observed in solids and structures subjected to high temperature under monotonic and cyclic loadings.
