v6.04.105 SSNV105 - Model BETON_GRANGER_V: creep test taking into account relative humidity and aging.

Summary:

This nonlinear quasistatic mechanics test case simulates a uniaxial creep test. Its objective is to validate the « Granger » behavior relationship, making it possible to model the natural creep of concrete. This model makes it possible to take into account the effects of humidity and aging.

This is a hardware test case, carried out using the SIMU_POINT_MAT command.

The stress applied is constant. The effect of humidity and aging is studied separately:

• ssnv105a: the relative humidity decreases linearly, the concrete is non-aging;

• ssnv105b: the relative humidity is constant and equal to the reference value, the concrete is aging.

The results obtained by*Code_Aster* are compared with the reference analytical solution.
