The electro-impulse de-icing (EIDI) system has wide development potential in the field of aircraft green de-icing. For the design and optimization of EIDI, it is quite necessary to study ice shedding criterion and simulate the de-icing process. Based on experimental observations and theoretical analysis, an improved ice shedding criterion considering ice/skin debonding and ice fracture is proposed in this paper. Nonlinear transient three-dimensional finite element models combined with the ice shedding criterion are established to simulate the de-icing process. The simulation method is verified by experiments and literature comparison. Compared with the traditional ice shedding criterion, the improved ice shedding criterion and de-icing simulation results in this paper are more reasonable and accurate. A parametric study is performed to determine the influence of ice strength parameters on de-icing effectiveness. The results of the parametric study can provide guidance for the design of a compound EIDI system with higher de-icing efficiency.
