1. Principle of the test

DEFI_MATER_GC allows you to generate from generate reinforced concrete materials from engineer data. In particular, with the options BETON_GLRC/CODIFICATION =” EC2 “, it allows you to create a material with the following properties calculated according to the concrete class and Eurocode 2:

Elastic property
Young’s module	\(E\)
Nonlinear Properties
Average compressive strength of concrete at 28 days	\({f}_{\mathit{cm}}\)
Tensile strength	\({f}_{\mathit{cm}}\)
Peak deformation under compression	\({\mathrm{ϵ}}_{c1}\)

The objective of the test case is to verify the values of the properties of the material created by comparing them to Eurocode 2 for the various classes of Eurocode 2.

In reality, this comparison was carried out manually for the first time and now we ensure the non-regression with respect to this reference situation.

In addition, the comparison focuses more exactly on the sum of the elastic properties on the one hand, and on the sum of the BETON_GLRC properties on the other hand.
