4. B modeling#
4.1. Characteristics of modeling#
The elements are modeled by discrete elements with 6 degrees of freedom DIS_TR.
Node \(\mathrm{NO2}\) is subject to an imposed force \(\mathrm{Fx}(t)\). We calculate the relative displacement of node \(\mathrm{NO2}\) with respect to the displacement of node \(\mathrm{NO1}\) and we compare it to the displacement calculated in the references [bib1] and [bib2].
The time integration is carried out with the Euler algorithm (time step: \({10}^{-3}s\)).
4.2. Characteristics of the mesh#
It is the same mesh as for modeling A.
4.3. Tested sizes and results#
Relative displacement of node \(\mathrm{NO1}\) (in meters).
