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. 2nd International Conference on Structural Integrity, ICSI 2017, 4-7 September 2017, Funchal, Madeira, Portugal Structural Characterization of 13 th Century Building placed in Trás os-Montes Region Patrícia C.

In the rehabilitation of a building, the study of the architectural and structural plants is very important, being, usually, necessary to do an architectural and structural inspection and mechanical campaign, to characterize the building completely. With the support of the architectural and structural designs it is easier to locate the damages and/or pathologies, understanding the structural behavior and the influence of the detected damages in the response of the structure, assessing the degree of risk of those damages in the structural stability of the building, leading to a better rehabilitation plan. It is imperative to know the mechanical characteristics of the materials that compose the structures, to repair, and if needed replace them, according to its features, conducti g to a sustainable rehabilitation, and preserving the original characteristics. © 2017 The Authors.
