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 and Exhibition 2018 Editorial R, Sunder* BISS (P) Ltd, Bangalore, India This special issue contains select papers from the 2 nd International Conference on Structural Integrity and Exhibition (SICE 2018) that was held in Hyderabad, India, July 25-27, 2018. The SICE series of biennial conferences are an initiative of the Indian Structural Integrity Society (INSIS) to bring together practicing specialists from industry, national laboratories and the academia. Given the sustained and rapid growth of the country’s industrial economy and considering the variety of strategic stake holders in energy, transportation, civil infrastructure as well as defence, the enthusiasm and energy to participate in SICE should not come as a surprise. Thus, SICE 2016 co-hosted by the Indian Institute of Science, Bangalore and Indian Institute of Technology, Madras under the Chairmanship of Prof. Raghu Prakash attracted over 150 participants. At SICE 2018, we had over 250 contributions and over 350 delegates. SICE 2020 will be hosted by the Indian Institute of Technology, Bombay (Mumbai), where even greater national and international participation is expected. The SICE meetings underscore the attractiveness of India as a conference destination. They offer 5-star hospitality and a single platform that unites hundreds of largely young stake holders from industry, R&D and academia, who carry the responsibility for structural integrity across the energy, transportation, civil construction and defence sectors of a rapidly growing industrial economy that is India. Thanks to government sponsorship and generous material co tributions from interested industrial p rtners, org nizers of SICE meetings have been able to keep Registration Fe aff rdable so that financial constraints don’t pose a challenge to participation. This s also made pos ible by the wholly voluntary effort of the entire organizing team. As a conseque ce, SICE2018 attracted several hundre abstract submissions, of which 190 were shortlisted for oral presentation and another 70 for the poster sessions. This is apart from the plenary and invited presentations by several scientists of global repute from Australia, Canada, France, Germany, Italy, Japan, Russian Federation, Sweden and the United States. The Conference enjoyed the active support of our outgoing Founder-President of INSIS, Prof. Ashok Saxena, who was a constant source of advice and useful suggestions to the Organization Committee. SICE2018 enjoyed financial support and encouragement from the Gover ment of India and from as many as a dozen industrial sponsors. The efforts © 2016 The Authors. Published by Elsevier B.V.
