    Identyfikacja parametrów sprężysto-plastycznych modeli gruntów metodą równoczesną
    (Wydawnictwa AGH, 2011) Fedczuk, Paweł
    The paper presents the concept of parameter specification of elasto-plastic soil models with using simultaneous method. This method uses nonlinear regression analysis of results of triaxial test (for chosen stress path) to obtainment all constants. Discuss of objective functions variants precedes the presentation of algorithm using combination of successive search method with Nelder-Mead's simplex technique. The stress path in triaxial test simulates step-iterative procedure, in which plasticity state is analyzed with using the Nayak-Zienkiewicz method. The presentation completes specific example of parameter identification of Nova-Wood model for results of standard shear path.
