v2.04.126 SDLV126 — Modeling viscoelastic damping with RIGI_MECA_HYST

Summary:

The objective of this test is to validate the extension of option RIGI_MECA_HYST of the CALC_MATR_ELEM method concerning linear viscoelastic materials under harmonic conditions. In this test, we check that option RIGI_MECA is not impacted, that we find the degraded case of hysterical damping and a cross-validation with the numerical results of Lucie Rouleau’s thesis was carried out.

The H, I and J models validate the use of kinematic loads (i.e. from AFFE_CHAR_CINE) that are not homogeneous with DYNA_VIBRA for harmonic calculations on a physical basis.
