3. Modeling A#

3.1. Characteristics of modeling#

We use a AXIS model.

3.2. Characteristics of the mesh#

The mesh is composed of quadratic cells and is shown in the figure below.

3.3. Tested sizes and results#

The cracking time is determined at each node of the line in contact with the corrosive medium. The crack times obtained are plotted as a function of the coordinate \(c\) in the figure below.

The crack time \({t}_{f}\) is tested at the point \(C\) obtained by the index model and by the BaBy model.
