Journal ArticleDOI
Physical analysis of the state- and rate-dependent friction law. II. Dynamic friction
TL;DR: In this article, an extensive study of dynamic friction at non-lubricated multicontact interfaces between nominally flat bodies, rough on the micrometer scale, made of identical polymer glasses, was performed at temperatures ranging from $20 to close below the glass transitions.
Journal ArticleDOI
Elastic-plastic indentation creep of glassy poly(methyl methacrylate) and polystyrene: characterization using uniaxial compression and indentation tests
TL;DR: In this paper, a shallow indentation made by a 750 µm radius steel ball at 25 °C was measured as a time-response to a prescribed loading history of the indenter.
