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.

The present research focuses on Bartolomeo Ammannati's Juno Fountain (1555) – a Late-Renaissance masterpiece whose eventful story made it moving around from its planned site, the "Sala Grande" in Florentine Palazzo Vecchio, to Pratolino Park, then to Boboli Garden. Finally, current fragments re-assembling and museography staging under the vaults of the National Museum of Bargello court in Florence has been set up a few years ago on the 5th centenary of Ammannati's birthdate – after careful historical research about the many vicissitudes of the Fountain. Although there isn't any location change expected for this Ammannati's artwork, investigations and researches are going on. Namely, the seismic performance of the reconstructed Fountain is to be checked with reference to the seismic hazard of the site, as provided by the Italian Code classification. To this objective, the previously done laser scanning which allowed a three-dimensional digital modeling to help re-assembling the Fountain, has been now adopted to perform the structural analysis. Consequently, a structural evaluation to check the setting's seismic behavior is currently under process. The research, developed by joining different knowledges and fields, is an exampl e of the importance of a multidisciplinary approach for preserving artifacts museums' collections.
