Abstract

In elastic body calculations using particles, non-structural particle distribution and non-uniform particle size are adopted. A result of Discrete Element Method (DEM) is used to create initial particle coordinates for the elastic analysis. Oscillation cycle of a beam is compared to the theoretical value. Convergence of the present method with respect to particle size is shown.
