THE CONCEPT OF EROSION STRENGTH
Abstract
The designer needs some numerical value of a property that represents the erosion resistance of a material. As of now, there is no single property that can be used for this purpose just as we use various properties to represent static, fatigue and creep loadings. Recent suggestions to use the strain energy of the material as given by the area of the stress-strain diagram from a simple tensile test for this purpose have a few limitations such as strain rate effects, environmental effects (temperature and corrosion) and the scarcity of stress-strain data under these conditions. In order to overcome these limitations, a new concept known as erosion strength is introduced and it is defined as the energy absorbed by the unit volume of a material up to fracture under the action of the erosive forces in various environments. The methods to determine the erosion strength from an erosion test are outlined.
