Explicit list

This method requires user to write down the lamina name, fiber orientation and number of successive laminas with the same fiber orientation, layer by layer. Alternatively, a layer can also be defined by the name of a sublayup. A sublayup must appear before the layup where it is referenced.

A template for one layer is:

<layups>
  ...
  <layup name="...">
    <layer lamina="lamina_name"> angle:stack </layer>
    <layer lamina="lamina_name"> angle:stack </layer>
    <layer lamina="lamina_name"> angle:stack </layer>
    <layer layup="sublayup_name"/>
    ...
  </layup>
  ...
</layups>

Specification

<layer>

Material orientation and number of plies separated by a colon ‘angle:stack’. Default values are 0 for ‘angle’ and 1 for ‘stack’. If there is only one number presented in this element, then it is read in as ‘angle’, not ‘stack’, which is 1 by default.

lamina

Optional. Name of the lamina used in the current layer.

layup

Optional. Name of the sublayup used in the current layer. One and only one of lamina and layup should be used. ‘angle’ and ‘stack’ are not needed when layup is used.
