Abstract

It is difficult to analyze theoretically the dynamic fracture of concrete block because it is discontinuous fracture behavior. In this research, the impact fracture when the impact body collides with the concrete blocks is analyzed by using the Distinct Element Method (DEM). DEM is suitable for the analysis of the fracture behavior from the continuous body to the discontinuous body. In this analysis, the impact body size, speed and mass are changed, the fracture behavior as crack length, the penetration length, the destruction area in the concrete block, are clarified. From the results, the efficient method breaking the concrete block is drawn.
