| Abstract: | Experimental methods that offer point by point information regarding the investigated surfaces are preferred in the study of mechanical contacts. Such a method, advanced in [1-6], consists of investigating the contact model obtained by pressing a metallic punch against a flat, optically transparent, surface, by aid of laser profilometry. The variation of surface reflectivity is measured and used to accurately determine the shape and dimensions of contact areas. The present study employed the abovementioned method in order to experimentally investigate the contact behavior of various ball bearing balls, when pressed against the flat surface of a thick sapphire window with different normal loads. Experimental results were compared to theoretical predictions and good agreement was found between results. |
