The automotive industry is constantly looking for innovative techniques to produce lighter, more efficient, and less polluting vehicles comply with the increasingly restrictive environmental regulations. One of latest technologies, which still developing, based on fabrication body-in-white car parts through stamping aluminum tailor welded blanks. Tailor blanks (TWBs) are generally a combination...

The forming of low and high strength tailor welded steel sheets into preferred three-dimensional shapes by a homogeneous distribution plastic strain is highly difficult. In this work, the formability tailor-welded blanks prepared using laser welding (IS 513 CR2, IS CR3) tensile (AISI 304) were analyzed formation edge profile weld line movement was also examined. results showed decrease in chara...

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...

Formability of Tailor Welded Blank (TWB) is an important parameter which limits this kind of blanks usage. A forming criterion for tailor welded blank is presented based on the analytical model in this research. This criterion suggests Limit Strength Ratio (LSR) and Limit Thickness Ratio (LTR) for forming limit of TWB. When thickness ratio or strength ratio in tailor welded blank is greater tha...

A finite element model is proposed to investigate the effect of thickness differential on Limiting Dome Height (LDH) testing aluminum tailor-welded blanks. The numerical validated via comparison equivalent plastic strain and displacement distribution between simulation results experimental data. normalized LDH values are as a means quantifying influence for variety different ratios.
