Abstract

An Eulerian model is described that simulates orthogonal cutting of uni-directional fiber-reinforced polymer composites. The continuous finite element method and the discontinuous Galerkin method are combined to solve the governing equations. A progressive damage model is implemented to predict subsurface damage in the composite. A correction factor that accounts for fiber curvature is included in the model that incorporates the influence of fiber bending. It was found that fiber orientation has a dominant influence on both the cutting forces and subsurface damage. Good agreement was found between predicted cutting forces and subsurface damage and published experimental observations.
