v1.01.312 PLEXU03 — Validation of prestress cables in CALC_EUROPLEXUS

Summary:

The purpose of this test is to validate the chaining of a prestress cable tension calculation in Code_Aster with a fast dynamics calculation in Europlexus via the Code_Aster CALC_EUROPLEXUS macro command.

More specifically, it validates the following points in CALC_EUROPLEXUS:

• the use of BARRE elements

• taking into account the kinematic relationships resulting from DEFI_CABLE_BP

• Q4GG modeling with a group of elements containing triangles and quadrangles

• taking into account an initial state (movements and constraints)

• the calculation of the stresses from the initial displacement made by Europlexus

• the use of the EQUILIBRE keyword from ETAT_INIT

B modeling is also used to validate the calculation of option FORC_NODA in DEFORMATION = “PETIT_REAC” for the elements BARRE and in DEFORMATION = “GROT_GDEP” for the Q4GG elements from Europlexus.
