| Summary: | In this paper, a new investigation of crack propagation on a commuter aircraft
wing is discussed. The aircraft is a 19-seater multi-purpose commuter aircraft designed for a
mission on the remote area. The dynamic load acting on the wing is assumed as harmonic
load considering aerodynamic lift at a particular excitation frequency. A 3D wingbox CAD
model is developed for the numerical simulation. Extended finite element (XFEM) is applied to
analyse the crack propagation on the aircraft wing. The crack growth simulation is successfully
done, and the results are shown in some details. These results provided a novel insight on the
computational simulation of cracked wing structure under dynamic flight load. |
