Quasimolecular Dynamics Simulation for Bending Fracture Propagation of Laminar Composite Material
적층복합재료의 굽힘 파괴거동에 관한 준분자동력학적 해석
Abstract
Recently, quasimolecular dynamics has been successfully used to simulate the deformation characteristic of actual size material. In quasimolecular dynamics, which is an attempt to bridge the gab between atomistic and continuum simulations, molecules are aggregated into large units, called quasimolecules, to simulate the large scale material behavior. In this paper, a numerical simulation using quasimolecular dynamics has been performed to investigate the laminar composite material fracture and crack propagation behaviors in bending process of laminar composite material which is made of fictitious materials. The simulation of the bending of laminar composite material has clarified the effects of strength of material at outer surface upon the fracture behviors of the specimen.
