The Effect of Particle Shape Polydispersity on Deformability of Granular Materials
Abstract The shape of the particles that constitute a granular material significantly affects its deformation behavior. This study intends to identify the possible underlying microscopic mechanism of this effect. To this end, a distinct element code is employed to simulate a series of biaxial compression tests on specimens composed of pentagon particles with different levels of roundness and sphericity. The results show that the deformation modulus of the specimens decreases as the particles and the polygons enclosed by force chains turn more regular. Moreover, less isolated contacts are identified with the system getting more regular, contributing to the smaller deformation as well.
