Abstract
The goal of better fuel economy can be fulfilled by the use of technology like TWBs (Tailor Welded Blanks). TWB is a product of joining two or more than two materials before any forming operation. The limitations associated with TWBs are the weld line movement and reduced formability. The formability reduction of TWB is due to the thin/weak material involved in it and therefore the tensile study of the TWBs becomes an important aspect. In the present study, investigation of tensile testing of Similar Material Dissimilar Gauge TWB and Dissimilar Material Similar Gauge TWB has been done numerically. For the simulation purpose, ABAQUS/Explicit has been used. The results indicate that the thin/weak material governs the strength of the TWB because the failure or necking is observed in that particular side only. Also, it has been observed that the failure locations are found to be at the boundary of thin/weak base material and weld zone.
