Janssen effect and the stability of quasi 2-D sandpiles
, 2010 We present the results of three dimensional molecular dynamics study of global normal stresses in quasi two dimensional sandpiles formed by pouring mono dispersed cohesionless spherical grains into a vertical granular Hele-Shaw cell.

A study of the static yield stress in a binary Lennard-Jones glass
, 2003 The stress-strain relations and the yield behavior of model glass (a 80:20 binary Lennard-Jones mixture) is studied by means of MD simulations. First, a thorough analysis of the static yield stress is presented via simulations under imposed stress ...

Applying GSH to a Wide Range of Experiments in Granular Media [PDF]
, 2014 Granular solid hydrodynamics (GSH) is a continuum-mechanical theory for granular media, the range of which is shown in this paper. Simple, frequently analytic solutions are related to classic observations at different shear rates, including: (i)~static ...

Experimental Studies of The Back-To-Back Connected Cold Formed Steel Profile Bolted Joints [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2009 This paper presents the experimental test results of joints connecting the cold formed thin-walled steel profiles assembled in a pair, back-to-back cross section.

How collective asperity detachments nucleate slip at frictional interfaces
, 2019 Sliding at a quasi-statically loaded frictional interface can occur via macroscopic slip events, which nucleate locally before propagating as rupture fronts very similar to fracture.

Memory of the Unjamming Transition during Cyclic Tiltings of a Granular Pile [PDF]
, 2005 Discrete numerical simulations are performed to study the evolution of the micro-structure and the response of a granular packing during successive loading-unloading cycles, consisting of quasi-static rotations in the gravity field between opposite ...

Tensile and fatigue assessments of brazed stainless steel joints using digital image correlation
MATEC Web of Conferences, 2018 For mechanical tests of brazed stainless steel joints, the local deformation behaviour within the small area of the brazing seam is a major concern, because local strains cannot be detected with standard mechanical extensometers. The current study allows

On the capillary stress tensor in wet granular materials
, 2011 This paper presents a micromechanical study of unsaturated granular media in the pendular regime, based upon numerical experiments using the discrete element method, compared to a microstructural elastoplastic model.

Anomalous acoustic reflection on a sliding interface or a shear band [PDF]
, 2003 We study the reflection of an acoustic plane wave from a steadily sliding planar interface with velocity strengthening friction or a shear band in a confined granular medium.
