From the Composite Layup editor, click the
Plies tab.
If the plies in the composite layup are symmetric about a central
core, toggle on Make calculated sections symmetric. Enter
the plies in the ply table, starting with the bottom ply in the first row and
ending with the central ply. During the analysis
Abaqus
appends plies to the layup definition by repeating the entered plies (including
the central ply) in the reverse order to the top of the layup. Each generated
ply is labeled in ply stack plots and the output database by adding
Sym_ to the beginning of the repeated ply's original name.
This option cannot be used if the thickness or rotation angle for any
of the plies in the layup is defined using a discrete field.
For each ply, enter the following data in the ply table:
- Ply Name
-
The name of the ply.
Abaqus/CAE
displays this name when you are viewing the composite layup in
the Visualization module
and in a ply stack plot.
- Region
-
Select the region to which the ply is assigned. You can choose faces
from the viewport, or you can select a set that refers to a face. If you are
displaying a meshed dependent part, you can choose shell elements from the
viewport or select an element set. To choose elements from the viewport, you
must display the native mesh, and you must use the
Selection toolbar
to enable the selection of 2D Elements. You can also
select shell elements from a mesh part. For more information, see
Displaying a native mesh,
and
Filtering your selection based on the type of object.
- Material
-
The name of the material for this ply. Click mouse button 3, select
Edit Material from the menu that appears, and do either of
the following:
- Thickness
-
The ply thickness. Enter a uniform thickness directly in the table, or
click mouse button 3 and select to do
the following:
- Coordinate system
-
To define the coordinate system that will be used as the basis for the
reference orientation of the ply, do the following:
-
Click mouse button 3, and select Edit CSYS
from the menu that appears.
Note:
If you choose Edit Orientation from the
menu, you can define both the coordinate system and the rotation angle.
-
Select the base orientation. You can select the base layup
orientation, or you can select a coordinate system. If you select a coordinate
system, you must select the axis that defines the normal direction.
- Rotation
Angle
-
An additional rotation (counterclockwise about the normal direction)
for the ply's reference orientation. Enter a uniform rotation directly in the
table, or click mouse button 3 and select to do the following:
-
Select a predefined angle (0, 45, 90, or −45 degrees) to define a
uniform rotation.
-
Select Uniform, and enter an
Angle to define a uniform rotation.
-
Select a scalar discrete field to define a rotation that varies
spatially across the ply. You can also create a new discrete field by clicking
.
- Integration Points
-
The number of integration points, if you are specifying properties for
a composite layup integrated during the analysis.
