Development of induced anisotropy during shear deformation of plane granular assemblies is inves- tigated by introducing statistical characteristics of fabric and contact forces. The introduced micro-structural parameters are explicitly related to the measure of deviatoric load by considering condi-tions of static equilibrium. Verification of the relationship between parameters of anisotropy ...

La materia granular o materia granulada es aquella que está formada por un conjunto de partículas macroscópicas sólidas lo suficientemente grandes para que la fuerza de interacción entre ellas sea la de fricción.Colectivamente, este tipo de materia presenta propiedades que pueden semejar, dependiendo del tipo de fuerzas a las que esté sometida, a las del estado sólido, el estado ...
For granular materials, the recommended range, from the AASHO Interim Guide, is from 8000 t o 28 000 psi. For current flexible pavement design practice, the use of substitution ratios (SR) or layer equiva lents is advocated by the MSHA design procedure (2). Values for the various MSHA granular material
