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. ECF22 - Loading and Environmental effects on Structural Integrity Development of numerical-experimental model of connecting lugs and application on the lugs calculation of container terminals Đorđe Đurđević a , Nina Anđelić b , Taško Maneski b , Vesna Milošević-Mitić b , Ana Petrović b , Andrijana Đurđ vić a * a Collage of Applied Engineering Studies, 11000 Belgrade, Serbia b Faculty of Mechanical Engineering, 11000 Belgrade, Serbia Abstract The present paper describes numerical and xperimental methodology and development of the model for stre s and deformation state analysis of the connecting lug of container terminals. Numerical analysis was conducted by applying the finite element method in a ''KOMIPS“ software package. Experiments were performed at the Laboratory for stress and deformation measurements, Faculty of Mechanical Engineering, Belgrade University, using ''GOM“ equipment and ''ARAMIS'' software application. This paper demonstrates how it is possible to anticipate the results by applying FEM. This paper will present how experimental results can be predicted using the finite element method. The paper presents an overview of the existing research and review of previous results achieved in this field. Container termi al used to supply electrical nergy and management system of conveyor belts that are us d in the exploitation of he mining basins. Stress and deformation state analysi f the connecting lugs is carr ed out at th loading of the c tainer. © 2018 The Authors. Published by Elsevier B.V.
