Analysis of roping in AA6111 automotive sheet

The finite element method is used to numerically simulate the development of roping in an aluminium sheet AA6111 under stretching. The measured EBSD data are directly incorporated into the finite element model and the constitutive response at an integration point is described by the single crystal plasticity theory. The effects of spatial orientation distribution, imposed deformation path, loading direction, and inhomogeneous deformation within individual grains on the roping are discussed. Correlation between roping and individual texture components is also explored.
