Study of the glass deformation regime transition using indentation and scratch test

Abstract

The scratch tests are often used to study the friction and the wear phenomena thus to identify

locally the materials mechanical proprieties. In this context, our study aimsto contribute to the

understanding of the glass deformation regime transition using the scratch and the indentation. The

characterization of the scratching resistance and the comprehension of the scratching damage on the

basic of structural considerations and mechanicalanalysis were done. Tests of progressive linear

scratching and instrumented indentation, were performed on two glasses nuances using different

indenters and environments. The obtained results show a similarity of the scratch behavior of the two

glass types by comparison of their deformation. However, the obtained rupture critical load of the

borosilicate and the soda lime glasses were about 4.16 N and 5.34 N respectively. In addition, the

humid environment has a notable effect on the deformation regime in scratching.
