The interval intersection method for FE model updating

Abstract

In this work a method for finite element (FE) model updating based on interval analysis is presented. The interval analysis inclusion theorem is exploited to achieve a solution of the model updating problem. The solution algorithm is implemented in the automatic procedure named interval intersection method (INTIM). A basic and a refined version of the method and their implementations are presented. Solutions of a numerical example are provided to show the method capabilities compared with a classical sensitivity method. © 2011 Published under licence by IOP Publishing Ltd.
