At grain scale, single particle tests can be used to determine properties like Young’s modulus or crushing strength. With experiments like triaxial and oedometer tests, it is possible to examine the bulk mechanical behaviour of the granular material. Our experimental investigation is complemented by a numerical simulation where the discrete element method is used to compute the mechanical behaviour of such materials. In order to improve the simulation quality, effects such as rolling resistance, inelastic behaviour, damage, and crushing are also included in the discrete element method. Furthermore, the variation of the material properties of granules is modelled by a statistical distribution and included in our numerical simulation.||URI:||http://hdl.handle.net/11420/2792||ISSN:||2196-4378||Institute:||Konstruktion und Festigkeit von Schiffen M-10||Type:||(wissenschaftlicher) Artikel||Funded by:||The support of the DFG (Deutsche Forschungsgemeinschaft) under Grant Nos.
