silica2098: 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.
