In the present paper, an optimization of the draw-in of an automotive sheet metal part has
been carried out using response surface methodology (RSM) and space mapping …

Advanced high-strength steel (AHSS) is widely used in automobile manufacturing to reduce
the weight of vehicles, thereby improving fuel efficiency. However, the high yield and tensile …

For stamping of sheet metals and converting them to specific product shapes without failure,
the initial blanks should be correctly designed. Therefore, initial blank design is a critical …

Deep drawing is a forming process controlled by a number of parameters. The initial blank
shape is one of the most important process parameter that has a direct impact on the quality …

Blank design is an important task in sheet metal forming process optimization. The initial
blank shape has direct effect on the part quality. This paper presents a deformation based …

The aim is to determine—relating to a given forming process—the optimal material
(undeformed) configuration of a workpiece when knowing the target spatial (deformed) …

In the present paper optimization has been used to evaluate alternative sheet metal forming
processes. Six process set-ups were first defined in a hierarchy of designs and optimization …

In this paper, the influence of the initial anisotropy in achieving an optimal blank shape is
analysed using anisotropic mild steel (DC06) and nearly isotropic dual-phase steel (DP600) …

Consistent part geometry and minimal part dimensional variations are among the greatest
challenges in deep drawing operations. In this regard, spring-back is a phenomenon …
