5. C modeling#

5.1. Characteristics of modeling#

Segment \(\text{AB}\) is divided into 10 elements of the same length (10.) that form group POUTRE. The stitches are duplicated to form group BARRE.

5.2. Characteristics of the mesh#

Number of knots: 11

Number of meshes and types: 2 times 10 SEG2

5.3. Loading#

5.3.1. Calculations with assignment by value#

In the reference calculation, pre-deformation is affected on the beam elements.

EPX

\(1E-3\)

In the second calculation, pre-deformation is affected on the member elements.

EPXX

\(1E-3\)

5.3.2. Calculations with assignment by function#

The pre-deformation function is as follows:

EPXX

\(\mathrm{1E-5.}(X+Y+Z)\mathrm{.}\mathit{INST}\)

For the reference calculation (assignment by value), the value of \(\mathrm{1E-5.}(X+Y+Z)\) is calculated and assigned for each bar cell by taking the coordinates of its Gauss point (middle of the cell). The dependence on time is made by adding a multiplier function to the load.
