Models of Stress Fluctuations in Granular Media
We investigate in detail two models describing how stresses propagate and fluctuate in granular media. The first one is a scalar model where only the vertical component of the stress tensor is considered. In the continuum limit, this model is equivalent to a diffusion equation (where the rôle of time is played by the vertical coordinate) plus a randomly varying convection term. We calculate the...
متن کاملEstimating Finite Rotation Axes of the Radius for Forearm Rotation
This axis of radius rotation is widely employed in forearm rotation research, yet there are relatively few studies that have attempted to validate its position and proposed consistency. Studies that have reported a consistent radius axis have not considered sequential finite rotations – instead, they’ve calculated average axes over a large range of motion [3]. Others present very little data, s...

متن کاملMacroscopic stress from dynamic, rotating granular media
In this brief study, the stress is averaged over a two-dimensional rigid particle (disk) that is in contact with other objects via localized (point) contacts. In contrast to previous studies, the rotation dynamics of the particles is also taken into account here The stress contains four terms, (i) the static stress due to forces, (ii) the dynamic stress due to translational velocity fluctuation...
متن کاملMultilaminate Elastoplastic Model for Granular Media
A multilaminate based model capable of predicting the behavior of granular material on the basis of sliding mechanisms and elastic behavior of particles is presented. The capability of the model to predict the behavior of sand under arbitrary stress paths is examined. The influences of rotation of the direction of principal stress axes and induced anisotropy are included in a rational way witho...
