Create and Edit Laminates

Methods to create and edit laminates in HyperLaminate.

Create Laminates

Create laminate.
- In the browser, right-click on a sub-type under the Laminate branch and select New from the context menu.
- In the browser, right-click on a sub-type under the Laminate branch and select New from the File menu.
- In the browser, right-click on a sub-type under the Laminate branch, then click (New) on the toolbar.
A new laminate appears under the selected branch.

A default name and ID are assigned to newly created laminate.

The newly created laminate is automatically selected in the Laminate Browser and the Define/Edit pane takes on the appropriate configuration for the selected material sub-type.
If desired, a new name for the laminate may be entered in the Laminate name: field or the component color may be altered by clicking the color swatch and selecting a new color from the pop-up color palette.
For OptiStruct and Nastran user profiles, define the Stress and failure theory output: information as desired.
For all user profiles, define the Stacking sequence convention: information.
For Convention:, select a stacking sequence conventions.
If you select Repeat, specify how many times you want to repeat the entire block of entry rows.
For Ply thickness, select a thickness method.
- Choose Constant to have the Ply lay-up order table include a single thickness column: Thickness T1.
- Choose Variable to have the Ply lay-up order table include multiple thickness columns.
Note: The option to switch between constant or variable thickness is only available for certain laminate sub-types.
For Constant ply thickness, you can check the Common Thickness checkbox and specify a thickness to be used by all the entry rows.

Having checked the Common Thickness checkbox and entered a common thickness value, if you now uncheck the box, the thickness fields retain the common thickness value, but are now editable.
Complete the Ply lay-up order table.
Add/insert rows by completing the Add/Update plies: fields and clicking Add New Ply or Insert New Ply (for Insert New Ply, it is possible to choose to insert the ply above or below the selected rows).

Note:
The number of rows in the table is not the number of plies. This is governed by the stacking convention and the number of repetitions.
Data may be cut, copied from, pasted to, or deleted from selected fields using the toolbar, pull-down Edit menu or Ctrl+X, Ctrl+C, Ctrl+V and Ctrl+D, respectively.
Table rows may also be cut, copied from, pasted to, or deleted from, using the toolbar, pull-down Edit menu or Ctrl+X, Ctrl+C, Ctrl+V, and Ctrl+D, respectively.

Note:
Rows are always pasted above selected rows.

When multiple non-sequential rows are copied and then pasted, they will be pasted as sequential rows. For example, if rows 1 and 3 are copied and pasted at row 7, row 1 will be pasted as row 7, row 3 will be pasted as row 8, and what was row 7 will now be row 9.
For the OptiStruct and Nastran user profiles it is possible to define thickness and orientation fields in the Ply lay-up order table as designable and to assign design variables to them.
