General Description
Partly coded and probably not tested.
Element Type
- This element provides a linear, isogeometric, planar Bernoulli beam.
- Stress computation is not yet implemented.
Degrees of Freedom
The element uses two translatoric degrees of freedom (Disp_X, Disp_Y).
Parameter Description
| Compulsory Parameters | ||
| Parameter | Values, Default(*) | Description |
|---|---|---|
| MAT | EL-MAT int | Linking to a material input block |
| INT_TYPE_BEAM_2D_NURBS_BERNOULLI | FULL, USER | Control of integration type.
|
| CROSS SECTION | HEIGHT = float WIDTH = float |
rectangular cross section defined by height and width. A = h*w, Iy = h^3*w/12 |
| AREA = float IYY = float |
cross section defined directly | |
| 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_BEAM_2D_NURBS_BERNOULLI = USER |
Example of a Complete Input Block
EL-PROP 1 : BEAM_2D_NURBS_BERNOULLI MAT= EL-MAT 1 AREA=1.0 IYY=1.0 !or: WIDTH=1.0 HEIGHT=1.0 INT_TYPE_BEAM_2D_NURBS_BERNOULLI = FULL !or: INT_TYPE_BEAM_2D_NURBS_BERNOULLI = USER ! GAUSS_U = 3
Element Loading
The BEAM_2D_NURBS_BERNOULLI element is able to carry the following loads: Currently, nothing implemented.
Benchmarks
The main benchmark file in the Carat++-repository is
- '../examples/benchmark_examples/isogeometric/isogeometric_beam_bernoulli/iso_beam_bernoulli.txt'.
However, it is not part of the benmarktesting in RUN_Tests.
