| Abstract Scope |
A combination of physical experimentation as well as numerical simulation of bond rolling of aluminum sheets has been investigated in this study. The surfaces of the sheets were anodized in sulfuric acid with addition of indigo carmine in order to provide the oxide layer coloration as well as two specified oxide thicknesses. A progressive reduction per pass has been implemented in consecutive experiments at constant rolling speeds to develop different degree of oxide surface expansion leading to its fracture. A numerical model of the rolling process has been constructed utilizing DEFORM-3D software, wherein strain, strain rate, and stress fields were calculated. The calculated localized strain distribution reinforces with experimental data to determine the critical localized deformation criteria leading to different stages of the oxide layer fracturing. Classical metallography as well as electron microscopy techniques were used to evaluate the evolution of the oxide fracture as a function of deformation. |
