A New Method for Generating Arbitrary Polygonal Aggregate of Concrete

Abstract:

An algorithm for arbitrary polygonal aggregate generation is proposed based on secondary development of ANSYS in this paper. It is established on the basis of circular aggregate model, and the central angle is the control parameter to generate poristic polygon as the coarse aggregate of concrete. The concrete numerical samples with first gradation of aggregate and two gradation of aggregate are generated. The aggregate fraction of polygon sample is lower about 20% than the original circular aggregate sample in the statistical sense. The results show that the proposed method can simulate gravel aggregate appropriately as long as the central angle and the aggregate percentage of original circular aggregate sample is reasonable controlled.
