Fe-investigations on Shear Localizations in Granular Bodies within Hypoplasticity
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 analyz...
متن کاملShear strength of granular materials
RÉSUMÉ. La résitance des matériaux granulaires au cisaillement est généralement attribuée à l’anisotropie de la microstructure granulaire. La question de savoir comment l’anisotropie, et donc la résistance au cisaillement, dépend des propriétés des particules, reste ouverte. Dans cet article, nous proposons d’abord une synthèse sur le rôle des anisotropies de la texture et des forces vis-à-vis ...
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...
متن کاملRefraction of shear zones in granular materials.
We study strain localization in slow shear flow focusing on layered granular materials. A heretofore unknown effect is presented here. We show that shear zones are refracted at material interfaces in analogy with refraction of light beams in optics. This phenomenon can be obtained as a consequence of a recent variational model of shear zones. The predictions of the model are tested and confirme...
متن کاملEvolution of shear zones in granular materials.
The evolution of wide shear zones or shear bands was investigated experimentally and numerically for quasistatic dry granular flows in split bottom shear cells. We compare the behavior of materials consisting of beads, irregular grains, such as sand, and elongated particles. Shearing an initially random sample, the zone width was found to significantly decrease in the first stage of the process...
