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 Editorial Pedro Moreira*, Paulo J. Tavares INEGI / Faculty of Engineering Porto University, Portugal © 2017 The Authors. Published by Elsevier B.V. Peer-review under responsibility of the Scientific Committee of ICSI 2017. Research activity in Structural Integrity has seen an emer ing increase in recent years and spread throughout a number of exciting areas. ICSI focuses on all aspects and scales of structural integrity. This ranges from basics t future trends, with special emphasis on multi-scale and multi-physics approaches, and applications to new materials and challenging environments. Current research topics in the realm of Structural Integrity targeted by ICSI2017 include, but are not limited to Fracture and Fatigue, Stress Analysis, Damage Tolerance, Durability; Crack Closure, Nanoscale Damage, Material Ageing, Coatings Technology, Environmental Effects, Joining Technologies; Image processing fo SHM, New materi ls, Structural Integrity in Biomechanics and many other excitin res arch topics. In 2017, ICSI is proud to host the Second Multi-Lateral Workshop on Fracture and Structural Integrity, jointly organized by the Portuguese, Spanish and Italian groups on fracture. The Portuguese Structural Integrity Society and the Italian, and Spanish Groups of Fracture are strenuous scientific associations involved in several activities, under the umbrella of both the European Structural Integrity Society and the International Congress on Fracture. The second multilateral workshop is expected to increase the level of cooperation amongst these groups and increase the awareness to the research work done in the Iberian-Latin region of Europe on fractur and structural integrity relat d issues. This y ar, the ICSI organiz rs made an effort to return to the delegates part of their dedication and enthusia tic support from the previous editions, in the shape of increased visibility to the conference and scientific impact. ICSI2017 therefore launched a number of invitations to prominent researchers all over the globe to lecture on their own research fields, such as Prof. Alfonso Fernández-Canteli, Prof. Antonio Martín-Meizoso, Prof. Francesco Iacoviello, Prof. John W. Hutchinson, Prof. Pedro Camanho, and Prof. Manuel Freitas. ICSI2017 also started the organization of dedicated symposia and hosted the organization of ESIS Technical Committees annual meetings.
