Comments

  1. The ply option is used in combination with /STACK and /PROP/PCOMPP to create ply-based sandwich composite properties. See Example (Substack with /DRAPE) in /STACK.
  2. All elements defined in the ply must use the /PROP/PCOMPP property. The compatibility to material law of this option is similar to /STACK.
  3. The ply can be attached to a group of shell element (4 or 3 node shell or both).
  4. If both the grsh4n_ID and the grsh3n_ID are 0, the ply is void (no element).
  5. The orthotropy angle in
