Methamorphosis of Voronoi polyhedra as a definite measure
of the elastic-to-dissipative atomic displacement transition
Polimery 2001, No 5, 302
SummaryThe present method allows to describe the structure of non-crystalline and crystalline solids by constructing a Voronoi diagram. The method gives a detailed structural information about individual atom s and their surroundings. The deformation and methamorphosis of the Voronoi polyhedron is described for an interstitial atom in anfee crystal; an associated criterion is given for the elastic-to-anelastic transition. An extension of the idea to include amorphous materials is indicated. Voronoi tessellation has been applicd in the fields of materials science, physics and chemistry.
