A MICROSCOPIC CONSIDERATION OF THE SHEARING BEHAVIOR OF GRANULAR MATERIALS USING TWO-DIMENSIONAL MODELS

A MICROSCOPIC STUDY OF THE SHEARING MECHANISM IN GRANULAR MATERIALS SUCH AS SAND AND GRAVEL IS DESCRIBED. IN ORDER TO INVESTIGATE THIS MECHANISM BY THE MICROSCOPIC OBSERVATION THE INTERACTION BETWEEN PARTICLES, DIRECT SHEAR TESTS WERE CARRIED OUT ON A HORIZONTAL PILE OF ALUMINIUM RODS WITH VARIOUS DIAMETERS WHICH SIMULATED A TWO-DIEMENSIONAL GRANULAR MASS. A SIMILAR HORIZONTAL PILE OF RODS MADE OF PHOTELASTIC MATERIAL WAS USED TO MEASURE THE INTERPARTICLE FORCE TRANSMITTED DURING THE SHEARING PROCESS. A SIMULATION OF A TWO-DIMENSIONAL PARTICLE STRUCTURE IN THE INITIAL STATE BEFORE SHEARING WAS OBTAINED ANALYTICALLY BY APPLYING THE MONTE CARLO METHOD. IN THESE INVESTIGATIONS, THE INTERPARTICLE FORCE, THE FRICTIONAL ANGLE BETWEEN PARTICLES AND THE SLOPE ANGLE OF THE PARTICLE SURFACE AT THE INDIVIDUAL CONTACT POINT AGAINST THE GENERAL SHEARING PLANE WERE CHOSEN AS FUNDAMENTAL FACTORS AFFECTING THE SHEARING RESISTANCE OF THE MATERIAL. /RRL/
