Implementation and testing of two bee-based algorithms in finite element model updating Marrè Badalló, Roser Universitat Politècnica de Catalunya.

Many algorithms have been proposed, developed and enhanced in order to accomplish the demands of the updating process, mainly to achieve computationally efficient programs and greater results. The present Master Thesis proposes two new algorithms to be used in Finite Element Model Updating: the Bees Algorithms (BA) and the Artificial Bee Colony algorithm (ABC). Both were first proposed in 2005, are based on the foraging behaviour of bees and have been proved to be efficient algorithms in other fields. The objective of this Master Thesis is, thus, to implement and to test these two new algorithms in Finite Element Model Updating for a cantilever beam. The Finite Element Model and the algorithms are programmed, followed by the extraction of the experimental frequencies and the updating process. Results, comparison of these two methods and conclusions are given at the end of this report, as well as suggestions for further work. 2013-11-18 Minor thesis https://hdl.handle.net/2099.1/20685 PRISMA-93416 eng http://creativecommons.org/licenses/by/3.0/es/ Open Access Attribution 3.0 Spain application/pdf application/zip Universitat Politècnica de Catalunya
