Abstract
A continuous deformation measurement system of two dimensional granular materials displacement based on digital image correlation method (DIC) has been build up. Direct shear tests have been performed on standard sand in a special laboratory apparatus with different vertical pressure. Using DIC a pairs of consecutive photographs taken during the tests has enabled fields of displacement velocity and strain to be determined. Assumed the proportional of stress and strain, the direct observation of displacements and principle strains has been possible for a series of force of grains under shear at various stages in the direct shear test.
