Abstract: The transient response of aero engine blades under bird impact loads is analyzed with the contact??impactfinite element method by numerical simulat ion in this paper. The mechanism of contact??impact process is discussed.Simulation r esults in this paper are impo rtant for impr oving the anti??impact ing damage ability o f blades under birdimpact.
