Abstract

In this paper an explicit multiscale model for composite materials is introduced. Impact damage is a very nonlinear event which is difficult to model in implicit solvers. Predicting progressive failure in a composite can be done with ply level mechanisms and/or micro level mechanisms. This paper uses the Generalized Method of Cells as implemented within %ASA's Micromechanics Analysis Code. It is implemented by the code FEAMAC within the commercial code ABAQUS. The numerical results of various impact speeds on composite strips indicate good correlation with the experimental results of the damaged regions.
