TL;DR: In this article, a Taylor-type polycrystalline model was developed and implemented into ABAQUS/Explicit finite element (FE) code using VUMAT to calculate the crystallographic texture evolution during the hydroforming of an extruded aluminum tube.

TL;DR: In this paper, an axisymmetric model of tube hydroforming using a Fourier series based finite element method is provided, which considerably reduces the size of the global stiffness matrix and the number of variables, is employed to approximate displacements.

TL;DR: In this article, a generalized plane strain implicit formulation of the cross-sectional expansion of an extruded aluminum tube with pressurized fluid to fill a hydroforming die is presented, and the axial feed is implemented by imposing either a compressive force or strain in the tube length direction.

TL;DR: This Taylor-type polycrystalline model was used to predict the anisotropy coefficients of Yld96 yield function and this phenomenological anisotropic yield function was implemented into ABAQUS/Standard finite element code for the hydroforming simulation of a 6061-T4 extruded aluminum tube.
