| Abstract: | The computer simulation method for the composites with random polygon grains is presented. At the same time, the algorithm of auto-generating triangulation mesh is given based on the technique of the almost uniform mesh and randomly inserting points. Numerical examples illustrate that the algorithm is very effective. The algorithm can be extended to the materials with cracks and to 3-dimensional cases easily. |
