Fracture analysis of fuselage wing joint developed by aerodynamic structural materials

Abstract

Al-MMCs the best suitable for aircraft, marine, automotive, and structural applications due to their unique properties. Predominantly Al-MMCs is used in aircraft components and their structures due to its superior tribo-mechanical properties. Recent research advancements in built-up aerodynamic structures with the aluminium hybrid composites (AHCs) series have been considered both attractive and interesting. Present study airframe fuselage bracket modeled and simulated with different series of fibers, alloys, AHCs, and Al-MMCs as aerodynamic structural materials (ASMs). Fuselage bracket modeled in CREO 2.0, followed by static, fracture, and random vibrations simulated in ANSYS 14.5. Various ASMs simulated and compared their silent characteristics such as stress intensity factor, directional deformation, shearing of stress, and strain. Total deformation, Von-mises stress, and strain significantly are low for the fabricated Al6061 reinforced by 6 percent TiC with 3 percent SiO2 compared with other ASMs. The Al6061/6 %TiC/3 %SiO2 is the best-suited material for aerodynamic structural applications.
