ARBITRARILY POLYGONAL 2-D FINITE ELEMENTS

At present, the computational analysis of micromechanics used to single crystalis to divide a crystai into many triangular or quadrilateral finite elements. If we use thismethod to analyze polycrystalline materials, the computation work will be too massive。Experimental observations show that the deformation and slide state vary slowly inside everycrystal of the polycrystalline material. Therefore each crystal may be idealized to a polygonalelement and each crystal interface to an interface eleinent, in so d...
