Presented paper is concerned with the numerical modeling of quasibrittle materials such as concrete. Brancherie and Ibrahimbegovic are authors of a simple model capable of describing the behavior of a structure until localized failure. In this paper, we discuss the identification of the model parameters from results of the three-point bending test. This leads to an optimization problem, which is solved by the stochastic algorithm 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.
