Nanoindentation measurements data
Description
Load and depth measured with Berkovich diamond tip on fused silica material.
Data contains only cutted part of unloading indentation curve from silicaBerk
data (20-98 %, as recommended in
ISO 14577 standard). The relationship between Load (F) and Depth (h) is given by equation
F = \alpha (h - h_p)^{m}
, where h_{p}
is permanent indentation depth after
removal of the load, \alpha
is fitting constant related to the indenter geometry and
power law exponent m should be from (1,2) interval.
Usage
silica2098
Format
The data frame contains two columns:
- Depth
nanoindentation depth, in nanometers.
- Load
load, in milinewtons.
