AN EXTENED PHANTOM NODE METHOD FOR CRACK INTERACTIONS IN COMPOSITES

Full Article:

Failure of fibre-reinforced composite materials is usually preceded by the devel-opment of a network of cracks running through plies (matrix cracks) and between plies (de-lamination). Matrix cracks and delamination often interact with each other to form complex crack paths. A novel numerical method is developed to model all plies of the laminate by one element. Matrix cracks, delamination and matrix crack tips at the interface can all be explic-itly represented within such an element to achieve high accuracy modelling of the mechanism of interaction. A 2D element formulated based on this method has demonstrated good per-formance on the delamination/matrix crack interaction problem in a cross-ply composite laminate.
