碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 82 === On the field of civil engineering,discrete element method isusually used to analyze the behavior of rock and soil. Concrete elongs to the nonhomogeneous materail,so it is suitable to be lyzed by discrete element method.Besides deriving basic f constitutive law,this thesis also models the behavior ar material by a computer program based on the concepts te element method.Hopefully the program can model real exactly. Due to the difference of boundary condition,the program es two types of boundaries:displacement boundary and force ry.The effects of spin on the packing are also considered. ches of concrete behavior that are analyzed by granular are very few,so this thesis mainly focus on the roperties of concrete.The effects of confinement of volumetric strain have been modeled by this study.
