Honeycomb structures consists of cells with hexagonal shape repeated in two dimensions.
The following options can be defined:
Type: The type of honeycomb geometry.
Extruded: All cell walls have the same thickness. See also Figure 2.13: Extruded Honeycomb Geometry .
Expanded: Cell walls in the ribbon direction (perpendicular to the direction of expansion) have double thickness. See also Figure 2.12: Expanded Honeycomb Geometry.
Specify Volume Fraction/Foil Thickness: Whether to size the RVE by specifying the volume fraction or the foil thickness.
Volume Fraction: The fraction of space within the RVE that the honeycomb material occupies.
Foil Thickness: The thickness of the foil (sometimes referred to as wall thickness or paper thickness).
Side Length: The length of the cell edges.
Cell Angle: The angle of the cell in degrees (60 corresponds to a regular hexagonal cell, 90 to an over-expanded cell).
Thickness: Core thickness of the honeycomb panel.
Repeat Count: The number of times that the unit cell is repeated in X and Y direction.
Note: The ribbon direction corresponds to the x direction, while the expansion direction corresponds to the y direction.
