Height: \(h=1.00m\) Width: \(l=1.00m\) Thickness: \(e=1.00m\)

The following meshes are defined:

\(\text{S\_ARR}\) \(\mathrm{NO3}\mathrm{NO7}\mathrm{NO8}\mathrm{NO4}\)

\(\text{S\_AVT}\) \(\mathrm{NO1}\mathrm{NO2}\mathrm{NO6}\mathrm{NO5}\)

\(\text{S\_DRT}\) \(\mathrm{NO1}\mathrm{NO5}\mathrm{NO8}\mathrm{NO4}\)

\(\text{S\_GCH}\) \(\mathrm{NO3}\mathrm{NO2}\mathrm{NO6}\mathrm{NO7}\)

\(\text{S\_INF}\) \(\mathrm{NO1}\mathrm{NO2}\mathrm{NO3}\mathrm{NO4}\)

\(\text{S\_SUP}\) \(\mathrm{NO5}\mathrm{NO6}\mathrm{NO7}\mathrm{NO8}\)

The travel limit conditions imposed are:

On the side \(\text{S\_INF}\): \(\mathrm{DZ}=0\)

On the side \(\text{S\_ARR}\): \(\mathrm{DY}=0\)

On the side \(\text{S\_GCH}\): \(\mathrm{DX}=0\)

The load consists of the same drying field and the same FORCE_FACE applied to \(\text{S\_SUP}\). A constant temperature of \(T=20°C\) and a constant humidity of \(h=1\) are uniformly imposed on the structure.

We charge in compression from \(0\) to \(20\mathrm{MPa}\) in \(10s\). and we maintain the load for 1 year.

4.3. Tested sizes and results#

We test the values of \({\varepsilon }_{\mathrm{xx}}^{\mathrm{fl}}\) and \({\varepsilon }_{\mathrm{zz}}^{\mathrm{fl}}\) at node \(\mathrm{NO6}\), for the times 45, 245, and 365 days.
