Abstract
Electro Impulse De-Icing is an alternative de-icing concept which operates
based on electro-mechanical impulses. These impulses can be modeled by coupled transient electro-mechanical simulations using the finite element method, whereas the process of ice
shedding can be simulated with a simple interfacial shear stress criterion. In this paper, the
time-consuming coupled analysis is replaced by a structural simulation where the magnetic forces
are approximated by comparison with the coupled results. Although the adhesive de-icing criterion
serves to represent the de-icing process very well, it lacks the modeling of a realistic
dynamic response of the structure. Therefore, the simula- tion is extended by a cohesive
zone model in order to take into account multiple radially propagating cracks that occur in
combination with ice shedding. Numerical studies are performed for an ice-covered aluminium plate
and validated by experimental results. The influence of cohesive crack growth and adhesive
debonding on the structural response and
de-icing behavior is investigated.
