Abstract

A procedure for computing the surrogate response of Finite Element models based on kriging interpolation is presented. A set of computer experiments is run for random occurrences of a target material parameter in order to build the data set necessary to the calibration of the interpolation model. Kriging parameters are defined via the Matérn 5/2 variance function and via average functions related to the expected trend of Finite Element analyses to get data consistent with the physics of the simulated experiment. Application of the surrogate model is detailed for the case of pure mode-I bending of a symmetric Double Cantilever Beam bonded specimen and the effectiveness of the proposed procedure is demonstrated both in terms of accuracy and computational effort.
