Crashworthiness study of a civil aircraft fuselage section

Abstract: This paper studies the crashworthiness characteristics of a fuselage section and its improvement. A full-scale three-dimensional finite element model of the fuselage section is developed using a nonlinear finite element code, PAM-CRASH. The simulation is implemented to determine the structural deformation and impact response in terms of peak loads and acceleration peaks at the floorlevel, deformation mode, energy absorption, and structural integrity, and then to assess the crashworthiness of the fuselage secti… Show more

“…Many investigations use composite materials to improve the energy absorption capability for various structures as well as civil aircraft fuselage under impact loading. [26][27][28][29][30][31][32][33][34] Many studies have proposed experimental methods for determining the absorbed energy of composite materials using different specimens with different shapes as well as various impact speeds. 16,35 Feindler et al 18 used a compressive rate of 0.25 mm/s to test CFRP specimens in omega-shaped and plate-shaped specimens with three different laminate layups (45°and 0°).…”

“…Authors have considered several scenarios, including explosions, foreign object impacts or hard landing crashes [5]. During the latter, the vertical deceleration is critically influenced by the sub-floor structures [6]. In the commercial aircraft range, the highest contribution for kinetic energy dissipation stems from deformation of the main fuselage [7].…”
