In this paper, a semiclosed form of numerical solution is obtained for a slicing-impact edge loading on a multilayered composite airfoil. The analytical derivation of the governing partial differential equation simulates the transient event of the slicing process by considering the moving bird in the form of a soft-body impactor as it comes into contact with the rotating fan blades modeled as prestressed airfoil due to centrifugal force field. The oblique-impact formulation of a composite pretwisted fan blade includes the effect of both the contact-impact loads as well as the Coriolis forces. The consideration of coupled longitudinal–transverse elastic wave propagation in a rotating coordinate system is a key to correctly predict the impact response of a blade mounted on a rotor shaft. The dynamic loading on the airfoil and its transient response produced during the bird strike is determined by solving the coupled nonlinear dynamical equations governing the movement of the bird slice in the time domain using a sixth-order Runge–Kutta technique.
