2021, WearCitation Excerpt :Within the context of impacting solid bodies, the latter mechanism is generally categorised by either; damage due to multiple impacts from a large number of smaller solid bodies singularly and collectively impacting on a much larger body (known as erosion or erosive wear), or repetitive impacts from a single solid body on another where the length scales are more similar (known as impact wear). Impact wear has been formally defined in literature as damage to one solid body due to percussion, which is a repetitive exposure to contact by another, typically solid, body [1]. It is also referred to as: hammering, hammer wear, percussive wear, and other similar terms.
Analysis of elastic and plastic impact models
2018, WearCitation Excerpt :Those are the cycling impact wear test, low velocity impact test [2] and the erosion test [3]. It is shown [4] that impact of metallic elements at moderate loads causes work-hardening on the subsurface leading to cracks that are nucleated below the surface and it may also cause piling-up or sinking-in phenomena. These two aspects of plastic deformation affect the accuracy of contact size and plastic depth determination.
