It involves two main features: (1) coupling discrete element and higher order continuum finite element regions via an overlapping region; and (2) implementation of a finite strain micromorphic pressure sensitive plasticity model as the higher order continuum model in the overlap region. The third

Numerical instabilities arise due to the distortion of the FE mesh. In this work, deformation analyses of geomaterials using Smoothing Particle Hydrodynamics (SPH) method ar

The effects of hardening, softening, strain localization in shear or tensile rupture bands accompany the machine tools operation in the cohesive soil. The aim of this contribution is to provide simplified incremental analysis of

Failure in Granular Materials: Macro and Micro Views,e it easy to define the notion from a phenomenological point of view. On the other hand, this notion is essential for civil engineers since projects have to be designed so as no failure is expected to occur. We herein consider the failure mode related to the creation of kinetic energy, without chang

The stress-strain relationship for a granular assembly is determined by integrating the behaviour of the inter-particle contacts in all orientations. The cons

The question has now taken on a more important and practical relevance over the intervening years, this in part motivated by various forms of failure such as strain localization and diffuse instability in geomaterials. According to classical theories, failure is largely seen as a condition of
