New Opportunities to Determine the Rate of Wear of Materials at Friction by the Indentation Data
Успехи физики металлов, 2020 The article is concerned with the determination of physical plasticity δH (the ratio of the plastic strain to the total strain) and yield stress σS by indentation and the application of these characteristics for analysis of the wear rate W during the ...

On the indentation size effect in spherical indentation
Philosophical Magazine, 2006 Size effects in plasticity at small length scales have been widely reported in a variety of loading situations. The hardness size effect has often been cited as an archetypal example. The indentation size effect was clearly demonstrated by Lim and Chaudhri (1999) in spherical indentation experiments on Copper and subsequently in experiments on Iridium ...

Competing indentation deformation mechanisms in glass using different strengthening methods
Frontiers in Materials, 2016 Chemical strengthening via ion exchange, thermal tempering, and lamination are proven techniques for strengthening of oxide glasses. For each of these techniques, the strengthening mechanism is conventionally ascribed to the linear superposition of the ...
