v6.04.228 SSNV228 — Pre-tensioning a stud

Summary:

This test illustrates how to pre-tension a stud in Code_Aster. The methodology adopted consists in applying a relative displacement between a group of elements of the stud and a group of elements of the nut (between the two faces that are normally threaded). Two models are proposed:

• Modeling A: manual determination of the displacement.

• B modeling: automated determination of the displacement using macr_recal.
