CuZr biaxial compression 20% engineering strain

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 surfaces along z. The present surface is the free surface in positive z-direction. The surface was initially atomically flat. The glass was deformed with a rate of 1e8 s^-1 at a temperature of 100K. The temperature was controlled using a Dissipative Particle Dynamics thermostat. This dataset contains the surface at 20% engineering strain (side length ca. 79 nm). The simulations have been reported in the following publication: Hinkle, A. R.; Nöhring, W. G.; Leute, R.; Junge, T.; Pastewka, L.
