For grains with maximal symmetry (squares), the stress propagation in the packing localizes forming chainlike forces analogous to the ones observed for spherical grains. This scenario can be understood in terms of stochastic models of aggregation and random multiplicative processes. As the grains elongate, the stress propagation is strongly affected. The interparticle normal force distribution tends toward a Gaussian, and, correspondingly, the force chains spread leading to a more uniform stress distribution reminiscent of the hydrostatic profiles known for standard liquids" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "American Physical Society" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://link.aps.org/doi/10.1103/PhysRevLett.103.118001" , "dc.relation.ispartof": "© Physical Review Letters, 2009, vol. 103, núm. 11, p. 118001" , "dc.relation.ispartofseries": "Articles publicats (D-F)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Processos estocàstics" , "dc.subject": "Stochastic processes" , "dc.subject": "Anàlisi numèrica" , "dc.subject": "Numerical analysis" , "dc.subject": "Materials granulars" , "dc.subject": "Granular materials" , "dc.title": "Role of Particle Shape on the Stress Propagation in Granular Packings" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1103/PhysRevLett.103.118001" , "dc.identifier.idgrec": "011381" }
