Description
Summary:While significant progress in modeling of sintering has been accomplished since the original paper by Frenkel "Viscous flow of crystalline bodies under action of surface tension", there are still several issues that remain open. One of them is anisotropy during sintering. In this paper we present some recent developments that improve our understanding of sintering anisotropy based on simulations of a two- dimensional array of particles. A number of possible sources of anisotropy are examined and evaluated. . Bez obzira sto je napravljen znacajan napredak u modeliranju sinterovanja od originalnog rada Frenkelja ?Viskozni tok kristalnih tela pod uticajem povrsinskog naprezanja? vise pitanja je ostalo otvoreno. Jedno od njih je i anizotropije tokom sinterovanja. U ovom radu predstavljamo neke novije rezultate koji poboljsavaju nase razumevanje anizotropije i zasnovane su na simulaciji dvodimenzionog niza cestica. Proucen je i procenjen jedan broj mogucih izvora anizotropije.
