Hi Luc,
In the experimental test the lateral strain is measured by the strain gauge put on the position h/2 (h: sample height) of the cylindric sample. In the link below, you find the video in which it is demonstrated how the uniaxial test is performed.

In the pure elastic phase the numerical lateral strain and the
esperimental lateral strain are equal. But in the damage phase, they are
not equal. In the link below, you find the stress/lateral strain
(numerical and experimental) curves.

To conclude, i try to minimize the discrepencies between the
experimental latreal strain and the numerical lateral strain in the
damage phase.
Best regards.
Jabrane.
