Granular assemblies can experience complex failure patterns along a given loading path, with distribution of ephemeral inertial events marked by local outbursts in kinetic energy. However, investigating such mechanisms appears to be necessary understand how certain mode develops granular material. Using discrete element method, this study highlights several microstructure reorganizations before...

We study the effect of mergers in the force chain model describing the stress profile in static granular materials. Combining numerical and analytical calculations, we show that granular materials do not generally behave in an elasticlike manner; however, they may under specific conditions, which are elaborated. Nonelastic behavior resulting from the nonlinearity of the full force chain model i...
