摘要

The purpose of this study is to investigate the effects of particle stiffness on the mechanical response between a granular assembly and an acrylic cylinder under confined compression. Variations of wall strain are measured through strain gages at three given heights and used to calculate the relevant stresses through a generalized Hooke's law, Steel spheres and polystyrene spheres are selected to characterize the effects of particle stiffness, Experimental results show that a granular assembly of highstiffness particles is able to transmit more vertical force, dissipates less energy in the lateral deformation, and causes a smaller frictional effect between particles and wall.
