Creating a Core

You can create an insert to stiffen the part, either as a simple or as a variable core.

Note: This task is available in Composites Design and Composites Manufacturing Preparation.

About Variable Core
  1. From the Plies Design section of the action bar, click Core .
  2. Select the stacking.
  3. Select a solid as the Geometry.
  4. Select the material, a direction, and a rosette.

    Direction and Rosette orientate the insert cells. See About Rosette and Rosette Transfer Type for more information.

    A new sequence is created at the end of the Stacking. It contains the core and its definition.
  5. To create a variable core, press Variable Offset Core Definition .
  6. Press to define a variable core from a contour, height, and angle.

    1. Select the Base Contour.
    2. Key in a Height (h).
    3. Key in an Angle (a).
  7. Alternatively, press to define a variable core from contours and heights.

    1. Select the base contour (shown as 1). As it is the base contour, leave its Height to 0.
    2. Select the second contour (shown as 2) and its height (h1).
    3. Repeat with the third contour (shown as 3) and its height (h2).

    Tip: Use the context menu to remove an element or create a contour.

  8. If required, add junction lines.
    1. Click Edit Junction Lines.
      In the 3D area, potential junction lines are displayed.

      A red traffic light is displayed at the start of the current contour. It turns green when all junction lines have been proposed for all vertices.

    2. Click the green traffic light to validate all proposed junction lines.
    3. Click the red traffic light to reset the definition of junction lines.
    4. Click the red marker of a junction line in the 3D area to delete one given junction line.
    5. Click the red marker of a junction line in the 3D area to delete one given junction line.
  9. To create a variable core from contours and heights with a 90° wall, proceed as explained above, but select the same contour twice.

    Tip: Adapt the contour selection to the geometry. For example:

    or

  • The Variable Core is created after the Stacking, under Solid:CoreGeometry.
  • The Solid:CoreGeometry is hidden, only the Core is visible in the 3D area. This ensures a correct computation of the inertia, without having to manually hide the Variable core
  • The Variable Core can be edited from Variable Core in the Core dialog box, the Core been updated accordingly.
  • When a Core is created from a PartBody as Geometry (Pad), the representation of the Core is created while the PartBody is hidden.
  • When a Core is created from Solid:CoreGeometry as Geometry, the representation of the Core is created whileSolid:CoreGeometry is hidden.
