초록

This paper presents the development of 2-dimensional discrete element algorithm to generate circle element automatically and model line element. The program realizes any radius of circle element, single line element, and various types of polygons connected by single line element. Two examples are shown to verify the applicability of the developed program. One is to generate circle elements automatically without overlapping and piling up and the other is to develop a rockfall analysis example near the railway and verify the program with equilibrium of energy.
