Abstract:  
Introduction 'Morphology' is the science of shape. Shot peening necessarily involves the production of indentations in the component's surface. This article is concerned with the morphology of those indentations. The isolated indentations that are present in the early stages of peening have simple shapes. We can then apply classical geometrical procedures to quantify the shape parameters. Progressively, the indentations overlap and the morphology becomes correspondingly complex. Individual indentation identities become subsumed into a general picture of multiple deformations.
