Abstract:
Different numerical simulation methods on tailor-welded blanks(TWBs)forming process were introduced in detail The deep drawing of tailor-welded boxes with non-uniform thickness was simulated by ABAQUS/Explieit code and the influence of the weld properties and shape on the results of numerical simulation was researched.There were three weld treatment methods in finite element model of TWBs as follows:the weld was neglected,the shell element was usded for weld,and the solid dement was used for weld and the weld shape was simplified as trapezoid.All of the parent materials in three models were shell element.Comparing the material flow and the displacement of weld in three models and in experiments,the weld properties have little influence on the simulation results,while the weld shape has large influence on the simulation results.The model of TWBs considering the weld shape is consistent with the experi- ment results.
