Abstract
Recently, quasimolecular dynamics has been successfully used to simulate the deformation characteristics of actual size solid materials. In quasimolecular dynamics, which is an attempt to bridge the gap between atomistic and continuum simulations, molecules are aggregated into large units, called quasimolecules, to evaluate large scale material behavior. In this paper, a 2-dimensional numerical simulation using quasimolecular dynamics has been performed to investigate laminar composite material fracture and crack propagation behavior in the uniform bending of laminar composite materials. We verified that laminar composite materials deform quite differently from the case of homogeneous materials under bending deformation.
