Cylinder

The Cylinder realization is intended to generate a Mesh Independent realization where a realization within a defined space is wanted.

It has no options to change the Mesh during the realization.

Realization Details

Bar Diameter
These options will be unavailable if there is a property associated with the control, as the property will define the Diameter values independently from the realization.
Auto
Takes the minimum hole size to define the beam/bar cross section. The created property will use this value as the beam cross section dimension.
Input
Allows the Diameter of the beam cross section to be defined directly. The created property will use this value as the beam cross section dimension.
Pretension
An optional parameter that will create a pretension. The position of the pretension will be per element or per layer at the center of the element.
Initial Stress
The initial pretension stress value.

Diameter Factor
In some automated processes, the cylinder diameter is automatically set to the fastener shaft diameter. This leads to failed cylinder fasteners when the holes are properly modeled because the defined cylinder does not contain nodes. In such cases, the cylinder diameter factor has been introduced. This factor is set to 1.0 by default and is a multiplier for the cylinder diameter to increase the final cylinder diameter when necessary.

Center Realization
When enabled, the realization will be centered around the Connector Position. When disabled, the realization will be centered around the found Nodes. Figure 5 and Figure 6 demonstrate the difference.

Element Details

Create Head
Allows the creation of an element per hole or prevents it. Figure 7 and Figure 8 demonstrate the difference in the realization with these options.

Bolt Length
The definition of the length of the body element.
Figure 9.


Hole Gap
Creates a body element with a length defined by the distance between the holes.
Body Length
Creates a body element with a specified length.
Head Configs
The element type to be used in creating the head of the realization.
Head DOF
The degrees of freedom (DOF) defined on the head element. This is only available for Rigid type elements.
Number of Body Configs
The number of elements between each hole layer.
Body Configs
The element type between each hole layer. If it is greater than 1, it can be adjusted via a table. The Percentage Body Length allows the relative lengths of each of the Elements within the body to be defined. Figure 10 shows one element with Percentage Body Length set to the full length and another element with Percentage Body Length set to zero connected at the end.
Figure 10.


Body DOF
The degrees of freedom (DOF) defined on the body elements. This is only available for Rigid type elements.
Number of Body Extensions
The number of elements projected above the Shell element to half the thickness.
Body Configs
The element type in the body extension. If it is greater than 1, it can be adjusted via a table. The Percentage Body Length allows the relative lengths to be defined.

Connectivity

Consider Hole
Allows selected nodes to be limited to just those found on a hole or any of the nodes found within the Cylinder.

Combine Links
Allows all of the nodes found within each side of the virtual Cylinder to be combined into a Single Rigid or a Rigid per link.
