WebOn the suction side (back) ice failure mainly is due to the coalescence of numerous small cracks or crushing. The progressive crushing on the suction side and chipping on the pressure side are repetitive processes. Simulation model results are presented for propeller-ice interaction events over a systematically varied range of parameters.
