ABSTRACT: The collision occurring when a ball in free falling strikes an inclined metallic fixed surface is analysed in the present paper. The launching height ensures plastic deformations due to ball indentation of the immobile surface (body, plate). The prints are scanned using laser profilometry and next analysed. An interesting result arises from the study of the correlation connecting the angle between the impact velocity and the immobile surface and the symmetry axis of the permanent prints

KEYWORDS: oblique impact, coefficients of restitution, laser profilometry, plastic indentation
