Define a New Laminate

Use one of the following three methods to create a new laminate in HyperLaminate:

Method 1:

1.	Select a sub-type under the Laminates branch of the Laminate Browser.

2.	Right-click the selected sub-type.

A context-sensitive menu appears with one option: New

3.	Click New.

A new laminate appears under the selected branch.

Method 2:

1.	Select a sub-type under the Laminates branch of the Laminate Browser.

2.	Select New from the File pull-down menu.

A new laminate appears under the selected branch.

Method 3:

1.	Select a sub-type under the Laminates branch of the Laminate Browser.

2.	Click the New icon, , on the toolbar.

A new laminate appears under the selected branch.

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

The newly created laminate is automatically selected in the Laminate Browser and the Define/Edit pane takes on the appropriate configuration for the selected laminate sub-type.

3.	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.

4.	For OptiStruct and Nastran user profiles, define the Stress and failure theory output: information as desired.

5.	For all user profiles, define the Stacking sequence convention: information.

6.	For Convention:, select one of the following stacking sequence conventions.

Total

Symmetric

Antisymmetric

Symmetric-Midlayer

Antisymmetric-Midlayer

Repeat

7.	If you select Repeat, specify how many times you want to repeat the entire block of entry rows.

8.	For Ply thickness:, select Constant or Variable.

Note:

The option to switch between constant or variable thickness is only available for certain laminate sub-types.

If Constant is selected, the Ply lay-up order table includes a single thickness column: Thickness T1

If Variable is selected, the Ply lay-up order table includes multiple thickness columns:

Thickness T1

Thickness T2

Thickness T3

Thickness T4

9.	For Constant ply thickness, you can check the Common Thickness box and specify a thickness to be used by all the entry rows.

Having checked the Common Thickness box and entered a common thickness value, if you now uncheck the box, the thickness fields retain the common thickness value, but are now editable.

10.	Complete the Ply lay-up order table.

11.	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.

12.	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.

13.	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.

14.	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.

15.	Click Update Laminate to save the changes for the current HyperLaminate session. (It is important to remember that the HyperMesh database is only updated on exit from HyperLaminate.)
