4. Conclusion

The aim of this article is to present a number of nonlinear behavior laws commonly used in civil engineering. More specifically, the presentation focuses on identifying the various parameters on which the behavior laws depend, and on a few examples of applications at the structural element level.

• In the first part, the main types of material parameters encountered are presented and classified into three groups:

  • parameters characterizing the material's elasticity ;

  • the parameters defining the transition thresholds between the elastic and non-linear behaviour regimes;

  • the parameters involved in defining the evolution of variables representing the non-linear regime.

• In the second...
