Stacking sequence code#

This method requires users to provide one lamina name and the stacking sequence code.

A template is shown below.

<layups>
  ...
  <layup name="..." method="stack sequence">
    <lamina>...</lamina>
    <code>...</code>
  </layup>
  ...
</layups>

Specification

  • <lamina> - Name of the lamina used.

  • <code> - Stacking sequency code. Explained below.

Rules of writing the stacking sequence code

  • All fiber orientations should be put between a pair of square brackets []

  • Different fiber orientations are separated by slash /

  • After the right bracket, user can add ns to indicate symmetry of the layup, where n is the number of the symmetry operations needed to generate the complete layup

  • Successive laminae with the same fiber orientation can be expressed using colon like angle:stack, where angle is the fiber orientation and stack is the number of plies

  • If a group of fiber orientations is repeated, user needs to close them in a pair of round brackets ()

[0/90]2s

“0, 90, 90, 0, 0, 90, 90, 0”

[(45/-45):2/0:2]s

“45, -45, 45, -45, 0, 0, 0, 0, -45, 45, -45, 45”
