Determination of the yield function and its derivatives of the Barcelona Expansive model
Mohammadia Engineering school, Rabat, Morocco
The main purpose of this paper is to determine the yield function F of the Barcelona Expansive Model and its partial derivatives with respect to the stress vector σ, the suction s and the hardening parameter χ. These results are important by the fact that they are used to solve the elastoplastic problem of unsaturated expansive soils.
