v3.01.101 SSLL101 - Piping: HOVGAARD problem

Summary:

It is a linear elastic test, in static, of a three-dimensional non-coplanar pipe with bends. There is a dynamic test of the same structure (SDLX02) [V2.05.002].

We test the elements POU_D_T, TUYAU (SEG3 and SEG4) and TUYAU_6M (SEG3) using 5 models:

• modeling A: 92 elements POU_D_T (40 for an elbow), calculation with MECA_STATIQUE,

• C modeling: 28 elements TUYAU (SEG3) (5 for an elbow), calculation with MECA_STATIQUE,

• D modeling: 28 elements TUYAU_6M (SEG3) (5 for an elbow), calculation with MECA_STATIQUE,

• E modeling: 28 elements TUYAU (SEG4) (5 for an elbow), calculation with MECA_STATIQUE,

The loads are of the following types:

• gravity,

• thermal,

• nodal forces.
