Analytical Modeling of Liquid and Solid Particle Erosion

Abstract

The analytical model for the erosion of a brittle material by multiple particle impacts is revised in accordance with erosion tests conducted using liquid drops, 70 and 290 micron diameter glass beads, and uniformly-graded quartz sand impacting flat- faced specimens of boro-silicate glass directly and at an oblique angle and then microscopically examining the progressively- eroded surfaces. Weight-loss data are available for ultra-high molecular weight polyethylene, nickel-coated glass-fiber reinforced epoxy, and graphite-fiber reinforced epoxy specimens exposed to rain and sand erosion environments.
