  • Joints are extremely important! 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?
