Abstract Based on crystalline plasticity slip and strain hardening model, a rate-independent
polycrystalline plasticity model was developed and introduced into finite element
method. A “successive integration method” was firstly applied to the calculation
of the plastic strain in large deformation analysis. By this method, it is easily to
distinguish different resolved shear stresses and shear strain rate in different slip
systems. The orientation distribution function is discretized by normal distribution
function, and every FE integration points represent one crystal. Flanging earing
tendencies with different initial orientations were discussed and verified by
experiments. \{123\}$\langle$634$\rangle$ texture can lead to earing at 45$^{\circ}$
direction, while the \{100\}$\langle$001$\rangle$ texture at 0$^{\circ}$ and
90$^{\circ}$ directions. For the annealing aluminum sheet, the flange earing
tendency is not obvious due to the balance between two main textures.
