Abstract:

This study presents an extensive multiphysics analysis of aircraft structural components using the COMSOL Multiphysics simulation tool. The goal is to test the structural integrity, vibration behavior, thermal response, and fatigue performance of key aerospace components under real-world conditions. Researchers built a thorough finite element model that included material nonlinearity, geometric characteristics, and boundary conditions similar to those encountered in real aircraft situations. The results of static loading tests showed the main stress concentrations and the overall deformation patterns. Modal study also identified natural frequencies to ensure that resonance effects remain within the normal ranges of engine and turbulence-induced excitation. Thermal simulations were conducted to evaluate the impact of operational temperature gradients on stress redistribution and dimensional stability. A high-cycle fatigue test was also conducted to determine the service life and the parts most likely to fail over time. The results show that the integrated Multiphysics methodology is a dependable and effective way to forecast how well modern aircraft parts will work and help improve their design. This paper shows how simulation-driven development can make aircraft systems safer, reduce physical testing, and improve overall reliability.
