Laser welding has a large potential for the production of tailor welded blanks in the automotive industry, due to the low heat input and deep penetration. However, due to the small laser spot and melt pool, laser-based welding processes in general have a low tolerance for seam gaps. In this paper, five laserbased welding techniques are compared for their gap bridging capabilities: single-spot l...

The main objective of this research is to identify optimal printing strategies and PLA (polylactic acid) filament materials produce rapid prototype deep drawing tools. Additive 3D technologies have been applied for a long time tools, but the unique in that it uses conventional various reinforced with FDM (Fused Deposition Modeling) printers. advantage method easy print recycle does not require ...

The paper demonstrates the correlation between the chemical composition of steel grades and the hardness as well as the formability of laser welds generated with modern automotive high strength steel grades. At the very low heat input of industrial laser welding and the resulting extremely high cooling rate, the weld hardness is fully controlled by the carbon content of the base materials and n...

forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. in this research, forming limit diagram (fld) of ss304l sheet was obtained by abaqusfinite element software. in practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. forming limit di...

Although EK4 drawing steel is nowadays widely used to manufacture a great variety of parts, it exhibits marked normal and planar anisotropy that can make difficult control the process during its forming. In order achieve an accurate description elastoplastic material response in sheet forming operations, this work presents detailed damage characterization deep through two-step methodology invol...
