A CONSEQUENCE OF POST-IMPACT RADIAL PROFILE SHAPE OF INDENTATION. PART I - EXPERIMENTAL EVIDENCES

Abstract

The remnant imprints from the surface of a rotating disc collided by a dropping steel ball is experimentally analysed. The study of post-impact indentation performed via laser scanning technique revealed a systematic aspect concerning the radial profile of the imprint, namely a deviation from the slope predicted by the theory of elasticity in the region between imprint and the periphery of the disc.
