Description
  • The present paper deals with the parameter identification of the constitutive model introduced previously by the authors from the results of a three-point bending test. The model itself is capable of describing behavior of massive structures taking into account both the diffuse damage mechanisms as well as localized failure phenomena. As all parameters of the model have a clear physical meaning, the identification procedure can be split into a sequence of three problems, each related to a specific mode of the material behavior. The numerical optimization strategy is based on an adaptive approximation of the objective function by the Radial Basis Function Network dynamically evolved by minima located by a real-encoded genetic algorithm.
