  Two new elements based on Voronoi cell finite element model are developed for Stress Calculation of structure including large amount of voids.One is the element with crack initiating from the edge of void inside element,and another one is the element with crack initiating from outside to internal element.Analytical solution of stress components nearby Crack Tip is added to stress Polynomials applying to Complementary Energy Functional.
