The non-normality effect of magnesium alloy AZ31 is numerically investigated using the crystal plasticity approach. A homogenization-based finite element method is introduced to compute the macroscopic material behaviors with a crystalline scale structure. The strain path abrupt change method is utilized and the non-normality, which is the difference between the normal to yield surface and direction of plastic deformation, is quantitatively evaluated. The effect of activities of each slip system on the non-normality is discussed.
