Abstract: Based on Abaqus/Standard software, the finite element model and hybrid algorithm for multi-point 3D stretch bending profile of aluminum alloy were established. The dynamic explicit algorithm was used in stretch bending, and the static implicit algorithm was used for spingback prediction. The stress, strain and springback of the part were simulated by implicit method of Abaqus/Standard software. The forming experiment results valid the finite element model and the hybrid algorithm. The springback deviation between theoretically predicted value and the measured value decreases as the bending deformation increases in the vertical direction.

Key words: materials synthesis and processing technology, profile multi point stretch bending, finite element model, springback prediction
