Abstract
Magnesium alloys develop pronounced crystallographic texture and plastic anisotropy during rolling, which leads to earing during deep drawing of the rolled sheets. This phenomenon is modelled for the magnesium alloy AZ31 using the finite-element method in conjunction with a viscoplastic self-consistent texture model. To determine the model parameters the model is adjusted to measured stress–strain curves in tension and compression. The predicted earing pattern is found to depend not only on the initial texture at the beginning of the drawing process, but to a large extent also on the evolution of texture during drawing.
