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 = α (h - h_p)^{m}, where h_{p} is permanent indentation depth after
removal of the load, α is fitting constant related to the indenter geometry and
power law exponent m should be from (1,2) interval.

The data frame contains two columns:
nanoindentation depth, in nanometers.
load, in milinewtons.
