Abstract

The present paper proposes an experimental test rig and methodology for the optical evaluation of micro-contact parameters in the case of micro-indentation tests of elastic materials with rigid indenters. Micro-contacts between small steel punches, of various shapes (considered rigid) and the flat surface of a synthetic glass (considered elastic), were investigated experimentally. The dimensions of the micro-indentation imprints determined by aid of laser profilometry were compared to theoretical results yielded by theoretical models from literature, [1, 2, 4], and good agreement was found. In order to verify whether the contact took place in the elastic or plastic domain, the tested surface was rescanned after a longer period of time, and it was determined that no remnant imprint was left. This confirms that the test was conducted in the elastic domain.
