THE ESTIMATION OF PHYSICAL CHARACTERISTICS AND THE VISUALIZATION OF GRANULAR DISINTEGRATION METHOD FOR STONES USING VOXEL STRUCTURE

摘要

The present invention relates to a method for visualizing a granular disintegration using a voxel structure to perform mathematical modeling of physical property changes of stones according to the passage of time and visualizing the changes in three dimensions in order to visualize an exfoliation phenomenon due to granular disintegration of the stones. The method includes: (a) expressing particles of a stone as a hexahedral voxel and extracting the voxel having one or more exposed cross sections; (b) applying a weight to each extracted voxel depending on a direction of the exposed cross section; (c) automatically assigning an initial porosity and a granular disintegration threshold to the extracted voxels in step (a); (d) removing the corresponding voxel by determining that the granular disintegration is realized if a calculated porosity of the voxel is larger than the granular disintegration threshold based on a calculation result of (c); and (e) determining exposure to surrounding voxels if the voxel removed by the granular disintegration occurs during calculation. The method can effectively visualize the exfoliation phenomenon due to weathering in a stone structure made by various stones.
