Study of the Mechanisms of Sand and Dust Erosion

Abstract

The fundamental mechanisms by which erosion occurs in brittle solids have been examined. The erosion process in brittle solids is studied by considering the extent to which a single impacting particle produces fracture in the surface of a brittle solid. By drawing on recent work on the location of fracture in brittle solids, it is possible to predict the effect of such variables as eroding particle size and velocity, angle of impact, material properties, and residual stress. Also, in the case of glass it is possible to predict, approximately, the particle size at which a transition occurs from brittle to ductile behavior.
