Depth-sensing indentation tests in studying plastic instabilities [PDF]
This review surveys the phenomenon of plastic instabilities occurring in depth-sensing indentation measurements. Investigations presented focus on the characterization of Portevin-Le Chatelier type instabilities observed in different metal alloys during ...

Elastic modulus of claystone evaluated by nano-/micro-indentation tests and meso-compression tests
Toarcian claystone such as that of the Callovo-Oxfordian is a qualified multiphase material. The claystone samples tested in this study are composed of four main mineral phases: silicates (clay minerals, quartz, feldspars, micas) (≈86%), sulphides ...

Effect of strain rate on serrated load of indentation in Al-Mg alloy
Indentation tests are used to determine the local mechanical properties of materials. Previously, the indentation strain rate was correlated with the strain rate in uniaxial tests based on the hardness, which was the obtained load divided by the cross ...

Effect of loading strain rate on nano-indentation response of an aerospace grade epoxy polymer
Depth sensing indentation holds the promise of local mechanical properties determination. However, the number of studies on materials that exhibit time-dependent and hydrostatic pressure-dependent behavior is still scarce.
