v6.08.101 SSND101 — Behavioral law for viscous dampers on discrete elements

Summary:

We test the response of the nonlinear viscous damper behavior model DIS_VISC, of the « generalized Zener » type, cf. [R5.03.17], formulated on discrete elements for SEG2 or POI1 meshes.

Although it is a viscous law, it is the STAT_NON_LINE operator that is used for validation. The response of discrete elements supporting a viscous nonlinear law of behavior under a harmonic loading is analyzed. The models are as follows:

• 1. static in non-linear cyclic,

• 2. static in linear cyclic and calculation of the dissipation,

• 3. static nonlinear creep,

• 4. static non-linear, by modeling a MAXWELL shock absorber.

The models and discrete elements tested are in \(\mathrm{3D}\) with the DIS_Tet DIS_TR models and the elementary characteristics: (K_T_D_L, K_ TR_D_L, K_T_D_N, K_ TR_D_N, A_T_D_L, M_T_D_L, M_T_D_L), according to the type of mesh and element.

This behavior is also validated for dynamic solicitations in test case SDND107 [V5.01.107] with the operators DYNA_VIBRA, DYNA_TRAN_MODAL and DYNA_NON_LINE.
