Random particle model for concrete based on Delaunay triangulation
Abstract In this paper, an efficient simulation method for obtaining a random particle model for concrete is outlined. First, the ‘take-and-place method’ and its extension, the ‘directed searching process’, are discussed briefly and the shortcomings are indicated. A new method, the ‘divide-and-fill method’, appears to be more convenient, especially when only a small computer is used. In this simulation method the available space (two-dimensional) is divided in separate areas, using a Delaunay triangulation. These areas are filled with particles taking into account a given grading curve and gravel content. Comparison with physical concrete sections, obtained by means of image analysis, shows that the results of this method closely represent reality. The divide-and-fill method also yields a finite-element mesh in a quasi-automatic way.
