Development of Random Polygon Mesh Generation for Discrete Element Method

With rapid advances in computer hardware and visualization systems, geometric computing has an important role at every comer of science and engineering. As a part of it, the polygon mesh generation is adopted to model some materials realistically. This paper contains the results of the development of polygon mesh generation for the Discrete Element Method (DEM). A new simple polygon mesh generation scheme for the numerical model is presented and Delaunay triangulation is used for the basic modeling scheme. Current generation model can be widely used to predict the failure behavior for the quasibrittle material i.e., concrete structure using elementary inclusion level modeling of the concrete and the interaction between inclusions and matrix, rock behavior in the tunnel analysis, and the interaction between structures and foundations.
