    Abstract:
    The forced response of granular packings to point forces was experimentally measured and compared to recent models for force propogation in a granular material. 2D granular arrays made of photoelastic particles were used for the modeling. Spatial ordering of the particles was found to be a key factor in the force response. The propogative component of ordered packings was found to dimnish with the degree of disorder.
