cfg_abaqus_3_fastener

Description: Creates a CONN3D2 element.

This realization uses the prop_fastener.tcl property script.

This script is used while creating Abaqus Fasteners in the Spot panel. It does the following tasks.

•Organizes the realized weld elements into their respective components, based upon the link they are connected to. Thus, if a weld is created between comp_1(1) and comp_2(2), the script creates a component collector with the name HM_CONN3D2<id> and organizes all the welds created as links between these two components into this collector. This collector is later referenced as the element set while creating the Groups (Interfaces).
•Creates the following properties/materials collectors:
-HM_ConnectorBehavior<id>: This material collector is created with the *CONNECTOR BEHAVIOR card associated with it.
-HM_ConnectionSection_<id>: This property collector is created once per model (card image CONNECTOR SECTION). The property is assigned to each HM_CONN3D2 component collector and carries the material HM_ConnectorBehavior.
-HM_FastenerProperty_r_<radius in property>: This property collector is created with the *FASTENER PROPERTY card associated with it. It defines the RADIUS and the degree of freedom definition of the fastener.
•Creates Groups (HM Interfaces) with the name HM_FastenerInteraction<id> and with the *FASTENER card associated with it. The fastener connects two component collectors and refers to the fastener property card mentioned above. It can also show the link elements to which the weld elements are linked via the Automatic_Surface_from_components option.
-If any system option (Single System ,1- System per layer or 2- Systems per layer) is used in the Spot panel during realization, this script creates ORIENTATION systems in the current collector with the name HM_ORI<weld_id>_n<node_id>. A property HM_ConnectorSection_<CONN3D2 element id> is created and assigned per element. Depending on whether one or two systems per layer are created the property points to one or both systems.

Description: Creates hexa element with DCOUP3D elements projecting and connecting to the surrounding shell elements. This realization uses the shell thickness to calculate the hexa offset from the shell elements. In the case where the model is a 3T connection, the acm (equivalenced-(T1+T2)/2) realization will join the hexa elements.

This realization uses the prop_abaqus_acm.tcl property script.

This script is used while creating acm (equivalenced-(T1+T2)/2) / (detached-(T1+T2)/2) /shell gap in the Spot panel and adhesives in the Area panel. It does the following tasks.

•Organizes the realized weld elements [acm Equivalence-(T1+T2/2)] into the respective components based upon the *HEAD and the *BODY information of the weld. During realization of this configuration type a solid hexa element [C3D8] is connected to the shell elements by the rbe3 elements [DCOUP3D].
-A collector with the name C3D8_comp_<id> is created with the SOLIDSECTION card image associated with it. This component contains all of the solid C3D8 elements which are created during realization.
-A collector with the name DCOUP3D_comp_<id> is created, containing all of the DCOUP3D elements created as the heads to the weld element.

If this script is called during the realization of adhesives in the Area panel, this script creates the above two components by different names:

hexa_comp_<id> for the Hexa elements

rbe2_comp_<id> for the rbe elements

•The script also creates a property collector named prop_<id>, with the SOLIDSECTION card image associated to it. This property collector is referenced to the component containing the Hexa elements created during realization process (i.e. C3D8_comp_<id> in the case of spots, or hexa_comp_<id> in the case of adhesives).

Description: Creates a Node Set that contains the nodes that are selected to create the connector element, and creates an empty Element Set. Connector elements are not created for this realization type. Abaqus creates the required connector elements on its own.

This realization uses the prop_fastener_nodes.tcl property script.

This script is used while creating Abaqus Fasteners-Nodes in the Spot panel. It does the following tasks.

•Organizes the realized weld elements into their respective components, based upon the link they are connected to. Thus, if a weld is created between comp_1(1) and comp_2(2), the script creates a component collector with the name HM_HMCONN_<id> and organizes all the welds (Dummy element) created as links between these two components into this collector. This collector is later referenced as the element set while creating Groups (Interfaces).
•Creates groups with the card image *FASTENER, and assigns them the name HM_FastenerInteraction_<id>. The fastener connects two component collectors and refers to the fastener property card. The Automatic_Surface_from_components option is used to show the elements to which the weld elements are linked to.
•Creates the following properties/material collectors:
oHM_ConnectorBehavior<id>: This material collector is created with the *CONNECTOR BEHAVIOR card assigned to it.
oHM_FastenerProperty_r_<radius in property>: This property collector is created with the *FASTENER PROPERTY card assigned to it.
oHM_ConnectionSection_<id>: This property collector is created once per model (card image *CONNECTOR SECTION). The property is assigned to each HM_CONN3D2 component collector and carries the material HM_ConnectorBehavior.
•Creates the following sets:
oHM_FastenerNodes_Node_Set1: Contains the selected nodes for the Fastener.
oHM_HMCONN_<id>: This is the dummy elset. The connector element is created and collected based on the nodeset HM_FastenerNodes_Node_Set1 assigned to this elset. You can refer the elset to outputblock.
