Martens Hardness of CAD/CAM Resin-Based Composites
Applied Sciences, 2022 (1) Background: The properties of CAD/CAM resin-based composites differ due to differences in their composition. Instrumented indentation testing can help to analyze these differences with respect to hardness, as well as energy-converting capabilities ...

Exfoliated Graphite Reinforced PMMA Composite: A Study on Nanoindentation and Scratch Behavior
Journal of Nanotechnology, 2012 The present work aims to compare the scratch hardness (Hs) with the indentation hardness (HIT) obtained from nanoindentation measurements of exfoliated graphite/poly (methyl methacrylate) (EG/PMMA) composites. EG/PMMA composites with thickness 50 μm each

Indenter Tip Radius and Micro-Indentation Hardness [PDF]
, 2007 Using finite element method with the conventional J 2 theory and strain gradient theory respectively, the effect of the indenter tip radius on the micro-indentation hardness is investigated in the present paper. It is found that the former can not predict the size effect even considering the indenter tip radius, while the latter gives a good agreement ...

Indentation size effect and hardness of materials [PDF]
E3S Web of Conferences, 2023 In recent decades, the Indentation Size Effect (ISE), which manifests itself as a change in fixed hardness depending on indentation conditions, has become one of the most urgent problems of modern materials science.
