20.500.12556/RUP-944 An aproximate technique for damage identification in beams using nonlinear regression analysis of bending frequency changes This paper addresses the problem of damage identification in beam-like structures on the base of bending frequency changes. The identification of damage location and its depth is performed by use of regression relations between changes in natural frequencies and damage parameters. Input data for establishing the regression relations are collected using numerical analysis (FEA) of the beam structure with and without damage. The damage is simulated as a narrow open notch perpendicular to the beam axis. The efficiency and limitations of the proposed technique are assessed through a series of damage scenarios. damage identification finite element analysis nonlinear regression prepoznavanje škode metode true true false Angleški jezik Neznan jezik Delo ni kategorizirano 2013-10-15 12:05:24 2013-10-15 12:05:24 2024-03-01 11:59:24 0000-00-00 00:00:00 2009 0 0 str. 192-200 Fasc. 3 Tome 7 2009 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1584-2665 519.23 3665879 http://annals.fih.upt.ro/pdf-full/2009/ANNALS-2009-3-40.pdf 1 https://repozitorij.upr.si/Dokument.php?lang=slv&id=944 Fakulteta za management 0 0 0
