Abstract:

This work is concerned with numerical simulations of surface roughening in a polycrystalline aluminum alloy. Using 3D finite difference model, high-resolution simulations are conducted. Effects of loading conditions and grain size on surface roughening and mesoscale deformation processes in AL6061-T3 aluminum alloy under quasistatic uniaxial tension are investigated.
