This paper presents a microscopic investigation on the effects of initial anisotropy, drainage condition, and consolidation state on the mechanical behavior and strain localization of …
The diffused and localized instabilities in sand under drained biaxial loading have been analyzed here following a plane strain bifurcation framework, where the rate independent …
The sudden loss in load carrying capacity of a soil specimen from its homogeneous material response is coined as the onset of instability or bifurcation in geomaterials. A numerical …
The study presents a theoretical analysis of liquefaction instability in sands using Extended Mohr Coulomb model. Experimental observations reported in the literature have indicated a …
Subjected to external loads, granular materials experience severe deformation in a narrow zone before their failure. This phenomenon, which is called strain localisation or shear band …
The influence of perturbation magnitude and extent of area on the emergence of localized instability in sand specimens subjected to biaxial loading has been explored within a …
The present study focuses on finite element analysis (FEM) of instability in saturated sands. The numerical simulation is performed under undrained conditions on the saturated triaxial …
