Electromechanical ice protection systems (IPS) induce mechanical failure of ice layer. To design an efficient IPS, it is necessary to study the fracture mechanisms at play. This paper proposes an evaluation of the influence of stress and energy criteria on fracture propagation for different modes through numerical analyses and experiments.
