measurements at macro-, micro-, and nanoscale: a critical overview.
The most demonstrative properties to observe the effect of fillers are tensile strength, indentation hardness
, flexural strength, and flexural modulus.
"It is not as simple as a relationship to indentation hardness
; a scratch incident is dynamic, whereas an indentation hardness
test is static." Thus they considered the several types of loading that occur during a scratch test: compressive, shear, friction, and "traction" stresses, which are related to material fracture (for more information, see ANTEC[TM] 2007 technical paper "Relationship Between Surface Microstructure and Improved Scratch Whitening Resistance of Thermoplastic Polyolefins for Automotive Applications," by Hermel-Davidock, Seliskar, and Oelberg).
The Brinell indentation hardness
test was performed with a 1 mm diameter steel ball, with loads 49 and 98 N and loading time 30 sec:
This brochure contains durometers and durometer systems that cover the entire spectrum of indentation hardness
testing of rubber-like materials.
Volume three of the 15-volume series documents practices and test methods for measuring crack growth behavior and fatigue in metals, the effect of temperature and stress relaxation, elastic properties, indentation hardness
, residual stress, grain size, and specimen preparation.
First, the specimen thickness and indentation hardness
of the conditioned foam after a recovery time are measured.
Micro indentation hardness
Testing 81: Butterworth, London :p.
The indentation hardness
of minerals is sufficiently characteristic to be used as a diagnostic tool; to measure it, a hard object under a known load is pressed into the surface of the substance to be tested.
The output of these hardness testers is typically a single indentation hardness
value that is a measure of the relative penetration depth of the indentation tip into the sample.
