A discussion on deformation of solids by the impact of liquids, and its relation to rain damage in aircraft and missiles, to blade erosion in steam turbines, and to cavitation erosion - Rain erosion properties of materials

“…On account of the damage occurring to materials in steam turbines, Honegger investigated the fatigue of materials caused by the repeated impact of water jets at velocities of 200 m/s. Although these investigations of material behaviour under high speed deformation are of great importance, they were developed further by only a few authors (Ackeret 1928;Ackeret & de Haller 1931;Vater 1937Vater ,1938Vater ,1951Schwarz 1941;Mantel 1937;Schwarz & Mantel 1943). Damage observed in 1945 on antenna coatings of B29 bombers and damage on radomes, air inlets and wing leading edges as well as on the front shields of modern high speed aircraft gave new impulse to this field of material research.…”
