Prediction of Tensile and Deep Drawing Behaviour of Aluminium Tailor-Welded Blanks
Tailor-welded blanks (TWB) are blanks with sheets of similar or dissimilar thicknesses, materials, coatings welded in a single plane before forming. Applications of TWB include car door inner panel, deck lids, bumper, side frame rails etc. in automotive sector (Kusuda et al., 1997; Pallet & Lark, 2001). Aluminium TWBs are widely used in automotive industries because of their great benefits in r...
متن کاملinvestigation of the effects of process parameters on the welding line movement in deep drawing of tailor welded blanks
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...
متن کاملeffect of fluid pressure on weld-line movement and thickness distribution in hydro-mechanical deep drawing of tailor-welded blanks (twbs)
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) ...
متن کاملFinite element analysis of tailor-welded blanks
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...
متن کاملinvestigation of forming limit and weld line movement in the forming of tailor welded blanks using experiment and numerical methods
the forming limit diagram (fld) is a useful method for characterizing the formability of sheet metals. in this paper, different numerical models were used to investigate the fld of tailor welded blank (twb). twbs were co2 laser-welded samples of interstitial-free (if) steel sheets with different thicknesses. the results of the numerical models were compared with the experimental fld as well as ...
