Abstract : An elementary theory of erosion is derived based on the assumptions of 'accumulation' and 'attenuation' of the energies of impact causing erosion. This theory quantitatively predicts the relative intensity of erosion as a function of relative time and this prediction is in fair agreement with experimental observations. Since the intensity of collision, the distance of shock transmission and the material failure are all statistical events, a generalization of the elementary theory is suggested. Some of the practical results of this theory are the predictions of the cumulative depth of erosion, the determination of erosion strength and the method of correlation with other parameters such as liquid properties and hydrodynamic factors. Modifications of this theory for brittle and viscoelastic materials are also suggested. (Author)
