5. C modeling#
5.1. Characteristics of modeling#
The model is identical to that of modeling A: same geometry, same boundary conditions. The load stresses the material in tension and then in compression (load No. 1 in modeling A).
The concrete is modelled with the Mazars damage model in 1D version [R7.01.08]. All material parameters are temperature dependent.
The DEFI_MATER_GC command makes it possible to determine the parameters necessary for the law of behavior. The only data required for the order is the constraint: \({F}_{\mathit{cj}}\).

Notes:
The values of the characteristics of the concrete material are not physical s. C*e test case is a non-regression test case.*
The changes, as a function of the temperature, of the various parameters are constructed from the command DEFI_FONCTION.
5.2. Tested sizes and results#
The quantities tested are stress, damage, as well as the maximum temperature reached.
