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.
  • FULL: p+1 Gauss points are used (p = polynomial degree of the NURBS patch)
  • USER: the optional Parameter GAUSS_U defines the number of Gauss points
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:

Benchmarks

Currently, no main benchmark file in the Carat++-repository is available.
