Abstract

The paper deals with the theoretical and numerical analysis of granular assemblies. Introduction of the re-interpretation of classical continuum-mechanical state variables is followed by a summary of continua with higher degrees of freedom. Results of numerical experiments are shown to point out that classical continua cannot contain enough information for the reliable description of material behaviour and the application of higher-order continua seems to be much more reasonable.
