Multiscale approach for granular materials including an intermediate scale

چکیده
This paper proposes an advanced micromechanical model that introduces an intermediate scale (mesoscopic scale): elementary hexagonal patterns of adjoining particles. This is a breakthrough with respect to current micromechanical models that generally describe the material by a single distribution of contacts. In essence, such models can incorporate a variety of local physical mechanisms. In this paper, the occurrence of diffuse failure is investigated, and the existence of a broad bifurcation domain inside the plastic limit surface is verified.

Multiscale ‘tomography-to-simulation’ framework for granular matter: the road ahead
A roadmap is presented to transition seamlessly from an image to a predictive computational model for granular materials. So far, constitutive modelling in granular materials has been based on macroscopic experimental observations. Here, the point of departure is the basic granular scale where kinematics, contact forces and fabric control the macroscopic mechanical behaviour of the material. Ne...
متن کاملA nonlocal multiscale discrete-continuum model for predicting mechanical behavior of granular materials
A three-dimensional nonlocal multiscale discrete-continuum model has been developed for modeling mechanical behavior of granular materials. In the proposed multiscale scheme, we establish an informationpassing coupling between the discrete element method, which explicitly replicates granular motion of individual particles, and a finite element continuum model, which captures nonlocal overall re...
متن کاملMultiscale modeling and characterization of granular matter From grain kinematics to continuum mechanics
Granular sands are characterized and modeled here by explicitly exploiting the discretecontinuum duality of granular matter. Grain-scale kinematics, obtained by shearing a sample under triaxial compression, are coupled with a recently proposed multiscale computational framework to model the behavior of the material without resorting to phenomenological evolution (hardening) laws. By doing this,...
متن کاملMultiscale Analysis of Transverse Cracking in Cross-Ply Laminated Beams Using the Layerwise Theory
A finite element model based on the layerwise theory is developed for the analysis of transverse cracking in cross-ply laminated beams. The numerical model is developed using the layerwise theory of Reddy, and the von Kármán type nonlinear strain field is adopted to accommodate the moderately large rotations of the beam. The finite element beam model is verified by comparing the present numeric...
متن کاملTowards Completeness, a Multiscale Approach of Confined Particulate Systems
Numerical simulation and computational visualization of the failure characteristics of confined granular assemblies, e.g., sand, gravelo ro ther types of loose aggregates, is the focal point of this publication. In general, standard continuum descriptions are exhausted if applied to loose granular materials, while discrete formulations fail to describe huge overall particulate structures. We pr...
