Unified Description of the Mechanical Properties of Typical Marine Soil and Its Application
Shock and Vibration, Volume 2017, Issue 1, 2017., 2017 This study employed a modified elastoplastic constitutive model that can systematically describe the monotonic and cyclic mechanical behaviors of typical marine soils combining the subloading, normal, and superloading yield surfaces, in the seismic response analysis of three‐dimensional (3D) marine site.

E3S Web of Conferences, 2016 Several researchers have reported that Bishop’s mean effective stress decreases in unsaturated soils under fully undrained cyclic loading conditions, and unsaturated soils are finally liquefied in a similar manner as saturated soils.

A Mathematical Approach to Establishing Constitutive Models for Geomaterials
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 The mathematical foundation of the traditional elastoplastic constitutive theory for geomaterials is presented from the mathematical point of view, that is, the expression of stress‐strain relationship in principal stress/strain space being transformed to the expression in six‐dimensional space.

Consolidation of Clay and Compaction of Sand : An elasto-plastic description [PDF]
, 2004 Naturally deposited clays/sands are mostly found in structured, and usually also in overconsolidated states. Furthermore, they exhibit what is more or less a condition of anisotropy.

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 5, Page 1420-1436, 10 April 2025.ABSTRACT In this work, a fatigue crack propagation model is proposed using the two‐dimensional discrete element method (DEM). The challenge lies in describing the small progressive fatigue crack growth within a single cycle, which is typically much smaller than the size of the smallest particles, making it difficult to continuously capture the loss of ...

Revisiting strain localization analysis for elastoplastic constitutive models in geomechanics
International Journal for Numerical Methods in Engineering, Volume 125, Issue 24, 30 December 2024.Abstract The localization of deformations plays a crucial role in the failure of granular materials. Concerning classical continuum constitutive models, the localization of deformations is considered to be connected to the loss of ellipticity of the governing rate equilibrium equations, and entails mesh sensitivity in finite element simulations.

Accurate prediction of spring-back phenomenon by subloading surface mode [PDF]
, 2019 The subloading surface model possesses the distinguished capability to describe the plastic strain rate for the rate of stress inside the yield surface accurately and the stresscontrolling function to pull-back the stress to the yield surface even when ...
