**v5.01.107** SDND107 - Release and seismic excitation of a system with a non-linear viscous damper of the "Zener" type
=========================================================================================================================

**Summary:**

We test the response of the nonlinear viscous damper behavior model DIS_VISC, of the "generalized Zener" type, cf. [:ref:`R5.03.17 <R5.03.17>`].

The aim is to validate the viscous law in linear and non-linear dynamics. The following tests are carried out:


* A) in linear dynamics (operator DYNA_NON_LINE) in a case of letting go, using an assembly of linear discrete elements as a basis of comparison for the "Generalized Zener" law of behavior.


* B) in non-linear dynamics (operator DYNA_NON_LINE) with a sinusoidal acceleration then a zero acceleration.


* C) in transient non-linear dynamics (operator DYNA_VIBRA or DYNA_TRAN_MODAL with an Euler-type time diagram) with a sinusoidal acceleration then a zero acceleration. It's the same study as B. The lawsuit is also validated.


* D, E) in transient non-linear dynamics (operator DYNA_VIBRA or DYNA_TRAN_MODAL with two Runge-Kutta time schemes of order 5 and 3, with adaptive steps) with a sinusoidal acceleration then a zero acceleration. It's the same study as B. The lawsuit is also validated.

This behavior is also validated with the STAT_NON_LINE command in SSND101 [:external:ref:`V6.08.101 <V6.08.101>`].
