stiffness mapping

Published on 5 August 2022 at 14:23

For our G200 nanoindenter we recently bought the express-test option. Minfei and Shan are trying it out. Left you see a SEM image from a cement paste. Right you see the stiffness maping with the nanoindenter. 10000 indents done within minutes. Looks quite promissing. Size of image is 1x1 mm.

Is it also possible to measure the stiffness of asphalt specimens with nanoindenters? Maybe visco-elastic materials are more difficult, because the stiffness depends of the temperature and loading frequency

Yes, that is possible.
we have also a temperature stage.
I see only 2 small possible problems:
- the sample should be very flat (micrometer precission)
- the material should not stick to the tip.

Wow, that is impressive! is there a publication or more examples about that?
What was max load/depth of each indentation?
How long does it take to make 10'000 indentations map?
