6. D modeling

6.1. Characteristics of modeling

The modeling is 3D for the concrete ring and BARRE for the cable.

For the first calculation (EVOLNOLI), the cable is of type PASSIF/ACTIF: PASSIF to the group of nodes” ANCR1 “and ACTIF to the group of nodes” ANCR2 “. For the other two calculations (EVOLNOL2 and EVOLNOL3), the cable is of type ACTIF/ACTIF. In all cases, the linear friction BPEL is taken to be equal to \(\mathrm{0,01}\) and the curved friction to \(\mathrm{0,03}\).

The calculation consists of a single step: the cable is prestressed with CALC_PRECONT and a tension of \({10}^{6}N\) without anchor recoil, except in case EVOLNOL3 where the anchor recoil is equal to \(5.{10}^{-4}m\).

6.2. Characteristics of the mesh

The mesh contains 20 elements of type HEXA8 and 20 elements of type SEG2.

6.3. Tested sizes and results

The results tested are of the non-regression type to serve as a reference in modeling E and concern:

• The next move \(x\) and \(y\) to the N16 node at times 1 and 2;

• The stress values in the M193 mesh at integration point 1, at times 1 and 2.

(see values in § 7.3).
