Laminate Composites > Defining plies and a stacking sequence
Define a stacking sequence using Paste Anti-symmetric
Use the Paste Anti-symmetric command to create one new ply for each ply that is in the clipboard. However, unlike a normal Paste operation, the Paste Anti-Symmetric command does two things:
It reverses the order of the copied plies.
It changes the orientation angle to be anti-symmetric.(In the example below, for each ply with an orientation angle of 45 degrees above the plane of anti-symmetry, an identical ply with an orientation angle of -45 degrees exists below it.)
The following figure illustrates the use of Create New Ply , Copy and Paste Anti-symmetric to define a stacking sequence:
A through D = Ply Groups created as described in Using Paste.
E = Ply Group 5In the ply table, click Ply Group 4, right-click → Copy then right-click → Paste Anti-symmetric.
F = Ply Group 6In the ply table, click Ply Group 3, right-click → Copy then right-click → Paste Anti-symmetric.
G = Ply Group 7In the ply table, use shift-click or control-click to select groups 1 and 2, right-click → Copy then right-click → Paste Anti-symmetric.
H = Physical representation
I = Representation in the Ply Sketcher tab
