(2024) Degradation and fatigue life methods for ceramic matrix composite and nickel superalloy materials in gas turbine combustor liner. In: Proceedings of FAIM 2024, 23–26 June 2024, Taichung, Taiwan, Volume 1, Flexible Automation and Intelligent Manufacturing: Manufacturing Innovation and Preparedness for the Changing World Order, Springer Cham, Lecture Notes in Mechanical Engineering, December 2024, pp. 393-40097830317448152195-4356https://doi.org/10.1007/978-3-031-74482-2_44https://dspace.lib.cranfield.ac.uk/handle/1826/23379This paper investigates the durability of Ceramic Matrix Composite (CMC) and Nickel Superalloy materials in gas turbine combustor liners across different flight conditions. Thermo-mechanical and physical properties of CMCs are assessed and compared with selected superalloys (i.e., Inconel 625, Hastelloy X, SiC/SiC, Al2O3/B4C, and Al2O3/SiO2) using Finite Element Analysis (FEA). An integrated methodology employing Computational Fluid Dynamics (CFD) and FEA is introduced to analyze thermal stresses and fatigue life, establishing a direct connection between combustion dynamics and structural responses. The study addresses a research gap by thoroughly evaluating CMC materials in gas turbine combustor liners, offering valuable insights for material selection and design strategies in aerospace engineering. The findings enhance understanding of CMC behavior, showcasing their reliability and durability for gas turbine components and their usage for advancements in aerospace applications.pp. 393-400enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/3403 Macromolecular and Materials Chemistry40 Engineering4001 Aerospace Engineering34 Chemical SciencesCeramic Matrix Composites (CMCs)Nickel SuperalloysAerospace applicationsDurability assessmentConference paper5610251
