The inverse analysis method for identifying a nonlinear hardening function, which governs a plastic yielding of soil and rock materials in the framework of the elastoplastic theory, is presented. A concept of two-stage finite element based on the spatial discretization of computational space and hardening function space is introduced. The proposed inverse analysis can be classified as the output least-squares method. The Levenberg-Marquard method is utilized for the minimization of the goal function at hand. A numerical example is given for the hardening function identification with the modified Drucker-Prager yield criterion in the case of a simple compression triaxial test.
