3.2. Characteristics of the mesh#

Number of nodes:

209

Number of meshes:

10 of type HEXA20

42 of type QUAD8

The following mechanical boundary conditions are imposed:

\(\mathit{FIXE}\)

\(\mathit{DZ}\mathrm{=}0\)

\(\mathit{FIXE1}\)

\(\mathit{DZ}\mathrm{=}0\)

\(\mathit{ABFE}\)

\(\mathit{DY}\mathrm{=}0\)

\(\mathit{CDHG}\)

\(\mathit{DY}\mathrm{=}0\)

\(\mathit{DAEH}\)

\(\mathit{DX}\mathrm{=}0\)

\(\mathit{BCGF}\)

\(\mathit{DX}\mathrm{=}0\)

To simulate wetting, the load consists of the application of capillary pressure on the face \(\mathit{FIXE1}\) with a value \(\mathit{PRE1}\mathrm{=}37.1\mathit{MPa}\) which decreases over time.

3.3. Tested sizes and results#

The component

of the stress, the capillarity value \(\mathit{PRE1}\), the gas pressure \(\mathit{PRE2}\), and the damage variable \(D\) are tested at the times 0.5 and 1. at the group of nodes \(E\). The values tested are values at the nodes, which is why they greatly exceed \(6\mathit{MPa}\), the elastic limit of concrete, at the first moment of calculation.
