Abstract
The influence of the heat generation induced by stone impact events is shown to be significant for the damage process of organic coatings. Experimental results on different water-soluble coatings are presented, indicating a rise in surface temperature of more than 80°C during single impacts with kinetic energies of more than 0.01 J. This temperature dissipates within a few tens of milliseconds. The damage morphology is determined by brittle fracture processes and plastic deformation effects in the case of low and high impact induced temperatures, respectively.
