In this paper, a recursive Bayesian procedure is proposed to monitor the health of such structures through data collected by a network of optimally placed inertial sensors. As a main drawback of standard monitoring procedures is linked to the computational costs, two remedies are jointly considered: first, an order-reduction of the numerical model used to track the structural dynamics, enforced with proper orthogonal decomposition; and, second, an improved particle filter, which features an extended Kalman updating of each evolving particle before the resampling stage. The former remedy can reduce the number of effective degrees-of-freedom of the structural model to a few only (depending on the excitation), whereas the latter one allows to track the evolution of damage and to locate it thanks to an intricate formulation. To assess the effectiveness of the proposed procedure, the case of a plate subject to bending is investigated; it is shown that, when the procedure is appropriately fed by measurements, damage is efficiently and accurately estimated.<\/jats:p>","DOI":"10.3390\/s16010002","type":"journal-article","created":{"date-parts":[[2015,12,23]],"date-time":"2015-12-23T06:52:19Z","timestamp":1450853539000},"page":"2","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Damage Detection in Flexible Plates through Reduced-Order Modeling and Hybrid Particle-Kalman Filtering"],"prefix":"10.3390","volume":"16","author":[{"given":"Giovanni","family":"Capellari","sequence":"first","affiliation":[{"name":"Politecnico di Milano, Dipartimento di Ingegneria Civile e Ambientale, Piazza L. da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saeed","family":"Eftekhar Azam","sequence":"additional","affiliation":[{"name":"University of Thessaly, Department of Mechanical Engineering, Leoforos Athinon, Pedion Areos, 38334 Volos, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5111-9800","authenticated-orcid":false,"given":"Stefano","family":"Mariani","sequence":"additional","affiliation":[{"name":"Politecnico di Milano, Dipartimento di Ingegneria Civile e Ambientale, Piazza L. da Vinci 32, 20133 Milano, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1016\/j.mechrescom.2008.08.011","article-title":"Structural health monitoring\u2014What is the prescription?","volume":"36","author":"Achenbach","year":"2009","journal-title":"Mech.
