Fe-investigations on Shear Localizations in Granular Bodies within Hypoplasticity
نویسنده
چکیده
A spontaneous shear localization in granular bodies is investigated with a finite element method based on a hypoplastic constitutive model. To simulate properly the formation of shear zones, a hypoplastic model was extended by polar, non-local and gradient terms to take into account a characteristic length of the microstructure. Two different rate boundary value problems were numerically analyzed with an extended model.

Investigations of Shear Localization in Granular Bodies within an Anisotropic Micro-Polar Hypoplasticity
The paper focuses on the numerical analysis of the effect of texturial anisotropy on shear localization in cohesionless granular materials. For simulation of the mechanical behavior of a granular material during a monotonous deformation path, a hypoplastic constitutive model was used. To take into account a characteristic length of micro-structure, the constitutive model was extended by micro-p...
متن کاملSimulation of Shear Localization in Granular Bodies within Gradient-Enhanced Hypoplasticity
The paper presents a FE-analysis of a spontaneous shear localization inside non-cohesive sand during plane strain compression. The calculations were carried out with a gradient-enhanced hypoplastic constitutive law. The hypoplastic law can reproduce essential features of granular bodies depending on the void ratio, pressure level and deformation direction. To model the thickness of shear zones,...
متن کاملFE-Investigations of Micro-Polar Boundary Conditions Along Interface between Soil and Structure
ABSTRACT: The interface between granular bodies and structures is analysed with the finite element method and a micro-polar hypoplastic constitutive model. Shearing of an infinite long and narrow granular strip between two walls of different roughness under conditions of free dilatancy and constant vertical pressure is investigated. The constitutive model can reproduce the essential features of...
متن کاملFE-studies of a Deterministic and Statistical Size Effect in Granular Bodies Including Shear Localization
The numerical investigations of size effects in granular bodies during a quasi-static plane strain compression test are performed. To describe a mechanical behaviour of a cohesionless granular material during a monotonous deformation path in a plane strain compression test, a micro-polar hypoplastic constitutive model was used. It includes particle rotations, curvatures, non-symmetric stresses,...
متن کاملGranular hypoplasticity with Cosserat effects
This paper provides an extension to Cosserat mechanics of a recently proposed version of hypoplasticity [1], and this extension is achieved economically by means of a novel complex-variable formulation of Cosserat theory. The present work represents a compact synthesis and theoretical framework for both non-polar and polar hypoplasticity, and it encompasses various special cases considered in t...
