General Description
Coded and testing is in progress.
Element Type
- This element provides a geometrically nonlinear, isogeometric spatial cable.
Degrees of Freedom
The element uses the translatoric degrees of freedom (Disp_X, Disp_Y, Disp_Z) of the control points of the master element.
Parameter Description
| Compulsory Parameters | ||
| Parameter | Values, Default(*) | Description |
|---|---|---|
| MAT | EL-MAT int | Linking to a material input block |
| INT_TYPE_NURBS_BREP_CHORD | FULL, USER | Control of integration type.
|
| CROSS SECTION | AREA = float | area of the cross section |
| PRESTRESS | PRESTRESS = float | prestress of the cable element |
| Optional Parameters | ||
| Parameter | Values, Default(*) | Description |
| GAUSS_U | GAUSS_U = int | Number of Gauss point per element. Must only to be defined when INT_TYPE_NURBS_BREP_CHORD = USER |
Example of a Complete Input Block
EL-PROP 1 : NURBS_BREP_CHORD MAT= EL-MAT 1 AREA = 1 PRESTRESS = 4000 INT_TYPE_NURBS_BREP_CHORD = USER or FULL GAUSS_U = 4
Element Loading
As the NURBS_BRep_Edge_Cord element is embedded into a master element, it can carry all loads which can be assigned to the master element:
