Abstract
FE models offer a promising virtual alternative to study machining responses of composites, thereby allowing an informed selection of favorable cutting parameters. Appropriate mathematical schemes are needed to predict damage initiation in fibrous composites; Hashin and Puck failure criteria are the most commonly used for this purpose. This work focusses on the assessment of these criteria to predict ply-level damage in orthogonal cutting of unidirectional composites. A novel algorithm accounting for strain-softening after damage initiation is also proposed. Efficacy of the developed FE model is shown by simulating effects of the cutter tool on the damage of underlying workpiece.
