A Scheme about the Finite Elements Model with Voronoi Net Method for Rock Strata Dynamics

Abstract

The length of the crack lines are in Fractals with thier accumulated frequency. The crack paint is given on the middle point of a crack line. At the field on the self-similarity and contraction mPPING, the crack point is a key point with the charactaristic of cracks on its regions. After these crack points were looked upon as the summits of Delaunay triangles, it calculate Voronoi's polygons. lf the crack points are not enough, the area of the polygon becomes more larger.
The energy to colups a light mass is smaller than the heavy ones. Then, the polygons look upon as a finite elements. After the analysis, distributed pattern of broken hinge (edge) whichare the interfaces of polygons is similer to charastaristic of observed crack lines on a rock wall. This paper is a note of the geologycal information about themodeling of finite elements which is based on the“Rigid Body Spring Model”proposed by KAWAI.
