in this paper, the deep drawing process of tailor welded blanks is simulated using the finite element modelling and verified using the experimental results available in the literature. then the effect of die and material properties on the welding line movement is investigated. it is seen that the most effective material parameters on weld line movement are different between sheet metal thicknes...

use of tailor-welded blanks (twbs) in production has significant advantages such as weight and cost reduction. however, their application requires processes that increase their poor formability in comparison to base materials. one of these procedures is the use of fluid pressure in sheet metal forming. in this paper hydro-mechanical deep drawing process of tailor-welded low carbon steel (st12) ...

Tailor Welded Blanks (TWBs) made of dissimilar, uniform or non uniform thickness materials have potential applications in automobile industries for light weight materials in order to improve fuel efficiency and cost of carrier. The focus of this paper is to develop and present analytical model to determine total elongation of tailor welded blank (TWBs). The validation of this method is done by ...

A typical tailor-welded blank (TWB) is composed of several base metals, which might have di!erent mechanical properties as well as thickness. Moreover, a TWB contains a heat-a!ected zone (HAZ) which has quite di!erent mechanical properties from base materials. The forming behaviors of TWBs have been widely studied since they were "rst developed as a way of using collectible o!al. They are often...

This paper deals with some numerical simulation and experimental tests related to forming and springback of a rectangular part manufactured from tailor welded blanks. Final shape of the parts manufactured by tailor welded blanks is seriously affected by springback effect. This paper work is trying to prove out the important role of material rolling direction has on the springback reduction. The...

in this paper, the optimum shape of tailor-welded blanks (twb) is investigated. the optimization is performed for two different case studies. the first example is deep drawing of a twb with dissimilar materials and uniform thicknesses and the next example is deep drawing of a twb with similar materials and non-uniform thicknesses. the effect of blank optimization on the weld line movement is in...
