摘要：

A 2 Dimensional discrete element analysis is carried out with diametrical stressing condition to understand the fracture behaviour of particle compounds. The new surface generation and particle size distributions are also analysed to study an efficiency of the crushing system. Concrete spheres of 150 mm diameter with properties of B35 (35 N/mm(2) compressive strength) are chosen to represent particle compounds. The paper discusses the discrete element approach for crack propagation analysis and their correlations in particle compounds.
