Context:
For a description of how you can combine connector orientations and fastener
orientations, see
Defining the fastener orientation.
From the Edit Fasteners dialog box, display the
Property tabbed page.
Enter the Physical radius of the fastener to
define the radius of its circular projection on the connected surfaces.
Abaqus
uses this information to define the geometric section properties of the
fastener.
Enter any Additional mass that the fastener adds
to the model. The mass is assigned to each fastener and lumped to the fastening
points.
Display the Section tabbed page, and choose the
method that you will use to model each fastener.
Choose Connector section and select a
connector section to model the point-to-point connection with connectors. Like
other uses of connectors in
Abaqus/CAE,
the connection can be fully rigid or allow for unconstrained relative motion in
the local connector component directions. In addition, you can specify
deformable behavior using a connector behavior definition that includes the
effects of elasticity, damping, plasticity, damage, and friction.
Choose Rigid MPC to model a perfectly rigid
fastener with a rigid, or beam, multi-point constraint
(MPC).
If you choose a connector section that uses a basic, assembled, or
complex connection type to model the fasteners, you can request output of
connector element output variables. However, if you use a beam
MPC to model the fasteners, no output is
available from the fasteners.
Display the Connector Orientation 1 tabbed page
to define the local directions for the first node of the connector. The
Connector Orientation 1 tabbed page is available only if
you use a connector section to model the fasteners.
- In most cases
Abaqus/CAE
orients the nodes at both ends of the connector with the global coordinate
system; however, some connection types that are referred to by the connection
section require local directions. Click
to select a datum coordinate system that specifies local
directions at the first node of the connector. Click
to create the datum coordinate system if it does not already
exist.
- Do either of the following:
Choose No modifications to CSYS to use
the selected datum coordinate system.
If desired, choose Additional rotation
angle and specify an additional rotation angle and the axis about
which
Abaqus/CAE
will apply the additional rotation. The additional rotation (in degrees) is
applied to both directions orthogonal to the selected axis.
Display the Connector Orientation 2 tabbed page
to define the local directions for the second node of the connector. The
Connector Orientation 2 tabbed page is available only if
you select a datum coordinate system that specifies local directions for the
first node of the connector.
- Click
to select a datum coordinate system that specifies local
directions for the second node of the connector. Click
to create the datum coordinate system if it does not already
exist.
- Do one of the following:
Choose Use orientation 1 to define the
same local directions that you specified on the Connector Orientation
1 tabbed page.
Choose No modifications to CSYS to use
the selected datum coordinate system.
If desired, choose Additional rotation
angle and specify an additional rotation angle and the axis about
which
Abaqus/CAE
will apply the additional rotation. The additional rotation (in degrees) is
applied to both directions orthogonal to the selected axis.
