Nanoindentation Dataset for the Microscale Mechanical Property of Granites

This dataset contains the raw results of nanoindentation testing, which are used to determine the elastic and failure property of rock-forming minerals in granites, which then provides the input parameters for accurate grain-based modeling. The dataset is presented and utilized in the paper 'Thermally induced microcracks in granite and their effect on the macroscale mechanical behavior'. Full details of the experimental setup, procedure, and imaging analysis are able to be found in this paper.

The results of nanoindentation testing of different rock-forming minerals by different indents are contained within six files: Berkovich_quartz, Berkovich_feldspar, Berkovich_biotite, Cube corner_quartz, Cube corner_feldspar and Cube corner_biotite. In these files, the raw data of nanoindentation testing includes elastic modulus, hardness, maximum load fore, maximum contact area, and contact depth. These results are then applied to calculate the  elastic and failure properties of rock-forming minerals.
