Abstract

The distribution of aggregates is intensive at the bottom of concrete model but scarce at the top position when polygon aggregates are packed by traditional random walking algorithm. In order to simulate the randomness of aggregates distribution more effectively and realistically, a bidirectional walk method of random polygon aggregates is proposed to overcome the above shortage of the traditional method. Firstly, the method to judge whether or not polygon aggregates intersection exist during each aggregate packing cycle has been improved. Further, after all the aggregates move into the target domain, the reverse walk of aggregates is taken into account, which means the walk direction of the aggregates is changed to straight up from straight down. The main results obtained reveal that the distribution of polygon aggregates is more evenly in two-dimensional concrete model by the proposed method compared to the traditional one.
