A theoretical framework is presented for the statics and kinematics of discrete Cosserat-type
granular materials. In analogy to the force and moment equilibrium equations for particles …

We probe the origins of nonaffine deformation in discrete element simulations of densely
packed granular systems under biaxial compression, using a new local measure of …

A study is made of kinematic and static assumptions for homogenization in micromechanics
of granular materials for two cases. The first case considered deals with the elastic …

Geomaterials are widespread in nature as well as in engineering practice, for example in the
form of a naturally given soil or a synthetic manufactured building material. The failure …

In this paper, a new homogenization technique for the determination of dynamic and
kinematic quantities of representative elementary volumes (REVs) in granular assemblies is …

Despite the prevalent use of continuum mechanics for the modeling of granular materials,
the controversy surrounding the relationship between the properties of the discrete medium …

Publisher Summary This chapter aims to provide a brief introduction to the discrete element
methods (DEM) approach for granular materials. The presentation focuses on its main …
