    Abstract:
    We present experiments measuring vector contact forces in a two-dimensional (2D) granular system consisting of bi-disperse, photoelastic disks. Using a bi-axial test apparatus, we study the response of the system to isotropic compression, uniaxial compression and pure shear. We obtain normal and tangential force distributions for each case and find that different loading conditions give rise to different force chain structures and different normal force distributions. © 2005 Taylor & Francis Group.
