### Ni36.67Co30Fe16.67Ti16.67 0% strain (initial surface)

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of bi-axial compression of a single crystal Ni36.67Co30Fe16.67Ti16.67 solid solution. The initial configuration was a Ni36.67Co30Fe16.67Ti16.67 cube with side length 100 nm. The x- and y-directions of the simulation cell were parallel to the [-34-1] and [-5-27] directions of the crystal, respectively. The z-direction was parallel to the [111] crystal direction. The x- and y-directions were periodic, but the z-direction was free, hence the crystal...

### CuZr biaxial compression 10% engineering strain

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of bi-axial compression of a CuZr (50% Cu, 50% Zr) metallic glass. The initial configuration was a CuZr cube with side length 100 nm. The glass had been produced by quenching from the melt at a rate of 1e11 K/s under fully periodic boundary conditions. In the compression simulation, the x- and y-directions were periodic, but the z-direction was free, hence the glass had free...

### Self-affine synthetic surface

Tevis D. B. Jacobs, Till Junge & Lars Pastewka
This surface contains virtual measurements taken out of a large self-affine synthetic surface with Hurst exponent 0.8. The original surface had 50,000 x 50,000 data points and was created using a Fourier filtering algorithm. The surface was "measured" in block containing 500 x 500 data points with a variety of scan sizes ranging from almost the full surface with 100 μm width to 10 μm to 1 μm, with pixel sizes scaling accordingly. This surface...

### Synthetic self-affine topography scanned with a virtual spherical probe

Tevis D. B. Jacobs, Till Junge & Lars Pastewka
This surface contains a self-affine topography that has been scanned with a spherical virtual probe of radius 40 nm. The probe was lowered normal to the surface on each point of the reference topography (that is also included here) and the center of the probe was taken as the "measured" value of the topography. The reference topography has a Hurst exponent of 0.8 and was generated with a Fourier-filtering algorithm. This surface was used to...

These are surface profiles of ceramic flooring. The ceramic tile (ADJF250803, ASTM) was a reference tile that was used in the reference standard ASTM F2508-12a. There are 30 profiles generated from image analysis and measured by SEM. 10 profiles are from 250X magnification, 10 profiles are from 5000X magnification, and 10 profiles are from 100kX magnification. There are also 6 profiles measured by stylus profilometry.

These are surface profiles of quarry 1 smooth flooring. The quarry 1 (0T01881P, Daltile, Dallas, TX, USA) and quarry 2 (01 010 SM 1, Summitville, OH, USA) were commercial tiles, where the full composition was a trade secret, but they were known to include 15-25 wt% quartz, and quarry 2 also included abrasive grits on the surface, presumably to improve slip resistance. There are 30 profiles generated from image analysis and measured by SEM. 10...
