This Guide describes the application of Finite Element (FE) analysis for predicting the erosion of ductile materials. The basics of setting up an FE analysis for modelling erosion are discussed, covering such topics as element selection, analysis type, contact definitions, selection of material model, model parameter sensitivity, erosion predictions, additional outputs and modelling multiple particle impacts. Examples, mainly from erosion analyses of a Ti-6Al-4V sample impacted by a steel ball, are used to illustrate the pertinent points. The finite element package Abaqus has been used to produce the examples shown in this guide.
