Detection of sparse damages in plates

Sabourova, Natalia / Duvnjak, I. / Grip, Niklas / Damjanovic, D. / Tu, Yongming / Popescu, Cosmin / Ohlsson, Ulf / Elfgren, Lennart

Structural damage is often a spatially sparse phenomenon, i.e. it occurs only in a small part of the structure. This property of damage has not been utilized in the field of structural damage identification until quite recently, when the sparsity-based regularization developed in compressed sensing problems found its application in this field. In this paper we consider classical sensitivity-based finite element model updating combined with a regularization technique appropriate for the expected type of sparse damage. The validity of the proposed methods is demonstrated using simulations on a bridge. The pros and cons of these methods are discussed. ; ISBN för värdpublikation: 978-3-85748-169-7
