Abstract:Roping is a severe surface defect in aluminium alloy sheets that can affect the product’s surface quality. However, quantitative prediction of roping is still a challenge. This paper introduces an approach combining experiment and simulation to analyse the roping phenomenon quantitatively in aluminium alloy sheets. A white light interferometer is employed to acquire large-area surface morphology with a detailed description of the corresponding morphological image preprocessing method. The electron backscatter … Show more
