The known fatigue model of Paris-Erdogan was first used for conditions of multi-cycle water-drop impacts with a metallic surface. The model is supplemented by the structure-dependent characteristics of the material. Experimental data providing correctness of model application is presented. The applied problem of quantitative evaluation of the material durability in the conditions of the droplet impact and comparison of materials of different structural classes was solved in the work without costly bench tests.
