FE Investigations of Dynamic Shear Localization in Granular Bodies within Non-local Hypoplasticity Using ALE Formulation

Wójcik, M. / Tejchman, J.

Dynamic shear localization in granular bodies during plane strain compression and plane strain silo flow was investigated. Finite element calculations were carried out with a hypoplastic constitutive model enhanced by a characteristic length of micro-structure by means of a non-local theory. The FE-dynamic analyses were performed with the help of an Arbitrary Lagrangian-Eulerian formulation using an explicit time integration approach. Emphasis was given to the formation of the pattern of shear zone in the interior of granular specimens.
