O'Donnell, M.: Finite Element Modelling of a Multi-Stage Stretch-Forming Operation using Aerospace Alloys, PhD Thesis, University of Ulster (). Stretch Forming of. A process design approach for multi-stage stretch forming was proposed by combining the strain distribution method and finite element method (FEM) to determine the minimum stage number and.

This study aims to optimize the stretch forming process by determining the necessary tool motions with numerical analysis. For this purpose, finite element model (FEM) of the process is established. Material characterization and friction tests of mostly used aluminum alloys are conducted for input to the model.

For the finite element models, punch, die and blank holder are considered as the rigid tools whereas blank is the only deformable tool. In meshing the geometries, 1D shell elements are used with an element size of 2mm. The following fig 2 shows the simulation model. Fig.2 The finite element model 5.

Results and discussion Thus, the through-process finite element (FE) modeling considering heating, forming, unloading, and cooling is one of the key problems to research the manufacturing process of LDMSC. In this study, the through-process FE modeling of the warm flanging process of LDMSC using aluminum alloy was carried out based on the FORGE.

The crystal plasticity finite element method (CPFEM) is widely used to homogenize the discrete dislocations and analyze the macroscopic effects of dislocation slip, based on the continuum theory, which reflects the microstructural characteristics of materials [8,9,10,11].The mechanisms involved in the macro and micro-deformation of non-ferrous metal materials during tensile deformation have.

[Ricardo Alves de Sousa; Robertt A F Valente;].The results of the finite element analysis show that the higher effective stress-plastic strain curves of the weld metal and the heat affected zone results in the necking/shear failure mode.
