Forming Analysis

Explicit finite element procedures for the simulation of sheet-metal-forming processes are reviewed. Improved techniques for contact searching and contact force evaluation are then proposed and discussed. In the contact searching algorithm, a new contact territory definition is introduced and only node-to-segment contact pairs are defined, which makes the post-contact searching more efficient and easy to implement. For contact force evaluation, a novel approach is employed to make the simulation of sheet forming processes more accurate. The algorithms are implemented and examined via experiments.

Simulation Results

Numerical simulation is an effective method for predicting formability of metals, and the use of computer simulation enables a significant increase in the number of tool designs that can be tested before hard tools are manufactured. Based on dynamic explicit finite element software, finite element simulation of sheet metal forming was performed to investigate the applicability of applying hydrostatic pressure on blank in multi point discrete dies. Simulation results show that using the hydrostatic pressure on blank is apposite for the process of multi point discrete dies.

In this paper, computer aided engineering of some innovative sheet metal forming processes is reviewed. Because of the complexity of this process, numerical simulation becomes necessary for its analysis. The deformation behavior of sheet metal in forming process is numerically simulated using quasi-static implicit and explicit finite element codes. The main advantages of the finite element method are: the capability of obtaining detailed solutions of the mechanics in a deforming body, namely, stresses, shapes, strains or contact pressure distributions; and the computer codes, can be used for a large variety of problems by simply changing the input data.

The multi-step forward finite element method is presented for the numerical simulation of multi-step sheet metal forming. The traditional constitutive relationship is modified according to the multi-step forming processes, and double spreading plane based mapping method is used to obtain the initial solutions of the intermediate configurations. To verify the multi-step forward FEM, the two-step simulation of a stepped box deep-drawing part is carried out as it is in the experiment. The comparison with the results of the incremental FEM and test shows that the multi-step forward FEM is efficient for the numerical simulation of multi-step sheet metal forming processes.
