3.1. Characteristics of modeling#

Modeling AXIS

Loading and boundary conditions are modelled by:

  • On face \(\mathrm{D1}\), move to \(Y\) drawn

  • On face \(\mathrm{D3}\), imposed traction

In addition, a uniform and constant temperature of \(20°C\) and a uniform and constant drying field of 1 are imposed on the structure. The sorption‑desorption curve (user data) makes it possible to go from the drying variable to the humidity.

3.3. Tested sizes and results#

We test the values of \({\varepsilon }_{\mathrm{xx}}^{\mathrm{fl}}\) and \({\varepsilon }_{\mathrm{yy}}^{\mathrm{fl}}\) at node \(\mathrm{N5}\), for the times 45, 245, and 365 days.
