Research abstract
THE DISCRETE ELEMENT METHOD WILL BE APPLIED TO SIMULATE THE DYNAMIC RESPONSE OF SOIL BY MODELING THE SOIL AS A DISCRETE GRANULAR MATERIAL. THE INTERACTION AND MOTION OF EACH SOIL GRAIN WILL BE MODELED EXPLICITY. THE PROGRAM AUTOMATICALLY TRACKS THE MOTION OF EACH GRAIN. A PARAMETRIC STUDY WILL BE UNDERTAKEN TO DETERMINE THE DEPENDENCE OF MACROSCOPIC SOIL BEHAVIOR ON MICROSCOPIC PROPERTIES. AN EQUIVALENT CONTINUUM CONSTITUTIVE BEHAVIOR WILL BE DETERMINED FOR SOIL UNDER DYNAMIC LOADING CONDITIONS.
