摘要用分子动力学方法研究了二维颗粒堆中的凸多面体。休止角与颗粒的大小分散度有关。在堆的顶端下有一个最小压力，它强烈地依赖于堆的构建方式。计算结果和与实验结果的比较表明，颗粒堆不存在一般的压力分布。
Abstract Granular heaps in two dimensions are studied using the molecular dynamics method with convex polygons. The angle of repose shows a dependence on the size dispersion of the particles. There is a pressure minimum under the apex of the heap which depends strongly on the way the heap is built. The results and the comparisons with the experiments suggest that there is not such a thing as a generic pressure distribution for granular heaps.
