Presentation Title Surface Roughening by Plastic Deformation in Amorphous and Crystalline Solids

On-Site Speaker (Planned) Adam R. Hinkle
Abstract Scope Most natural and man-made surfaces appear to be rough on many scales. However, there is presently no unifying theory of the origin of roughness or the self-affine nature of the surface topography. One likely contributor to the formation of roughness is the process of mechanical deformation. In particular, the plasticity observed in mechanically driven amorphous and crystalline solids has been characterized by avalanches of irreversible rearrangements exhibiting a self-affine, power-law behavior. Using molecular dynamics we simulate the bi-axial compression of a metallic glass and a single crystal of gold. We extract the free surfaces during the deformation and characterize the roughness. Analysis of the power spectral density reveals Hurst exponents above 0.5 for both the amorphous and crystalline surfaces, and a similar self-affine scale invariance is found within the displacement correlations of the bulk during plastic deformation.
