Out-of-plane loads, fasteners, ply build-ups, heavy, … • Is multi-scale analysis essential? • What is the best approach to progressive failure analysis? • Is it essential to include both diffuse and discrete damage? • How essential is accurate representation of the microstructure versus idealized RVE? • What is the best approach to model z-pins? Stitches? • What if you don’t know the crack path ahead of time? P
