Rovisco Pais, 1, 1049-001 Lisboa, Portugal Abstract During their operation, modern aircraft engine components are subjected to increasingly demanding operating conditions, especially the high pressure turbine (HPT) blades. Such conditions cause these parts to undergo different types of time-dependent degradation, one of which is creep. A model using the finite element method (FEM) was developed, in order to be able to predict the creep behaviour of HPT blades. Flight data records (FDR) for a specific aircraft, provided by a commercial aviation company, were used to obtain thermal and mechanical data for three different flight cycles. In order to create the 3D model needed for the FEM analysis, a HPT blade scrap was scanned, and its chemical composition and material properties were obtained. The data that was gathered was fed into the FEM model and different simulations were run, first with a simplified 3D rectangular block shape, in order to better establish the model, and then with the real 3D mesh obtained from the blade scrap. The overall expected behaviour in terms of displacement was observed, in particular at the trailing edge of the blade. Therefore such a model can be useful in the goal of predicting turbine blade life, given a set of FDR data. Title of the issue: XIV INTERNATIONAL CONFERENCE ON BUILDING PATHOLOGY AND CONSTRUCTIONS REPAIR, FLORENCE, ITALY, JUNE 20-22, 2018 Guest Editors: Gianni Bartoli, Michele Betti, Mario Fagone, Barbara Pintucchi Department of Civil and Environmental Engineering (DICEA) Via di Santa Marta, 3 – 50139, Firenze, Italia The XIV International Conference on Building Pathology and Constructions Repair (CINPAR 2018), held in Florence (Italy) from June 20th to June 22nd, 2018, gathered researchers and structural engineering experts in the field of surveying, monitoring, analysis and repair of buildings from all over the world. Participants to CINPAR 2018 had the opportunity to share and acquire knowledge on new materials, techniques and construction technologies, and to exchange personal experiences on strengthening and repair of structures. The International Scientific Committee was involved in the review process which led to the selection of high quality papers covering the following topics: • recent surveying and diagnosis techniques for material characterization; • frequent construction defects; • identification and analysis of the main causes of defects, which knowledge is crucial for a successful repair action; • materials used to repair and strengthen existing structures; • innovative repair and strengthening t chniques of existing structures; Keynote speakers Francesco Paolo Di Teodoro, Pablo Eugenio Maturana Barahona, Grazia Tucci, Petr Š t ě pánek, Esequiel Mesquita, Siro Casolo, Enio Pazini, Humberto Varum and Alessandra Marini, which are renowned experts in their research fields, further enhanced the Conference prestige. The Organizing Committee thanks all the Authors and the Participants for their contribution in increasing the quality level of the Conference: we trust that the papers published in these Proceedings will be an impetus to stimulate further studies and researches in all the topics addressed in the Conference.
