Scrap-based production of Steel using Electric Arc Furnace (EAF) with possibility of 100 % scrap charges, offers a Circular Economy based solution to reduce CO2 emissions when compared to the integrated Blast Furnace (BF) + Basic Oxygen Furnace (BOF) route (1.81 tCO2/tsteel for BOF vs 0.23tCO2/tsteel for EAF). However, EAF production of sheet steel is […]

The ADSUP project further expands on the impact of the CAMBER project, reducing the lead time of tool tryout in the material forming industry. The tool cost for the manufacturing of components, i.e. in the automotive sector, has a huge impact on the total manufacturing cost, why a reduction of the effort and lead time […]

Abstract During the running production of automotive body components drifts in theprocess window is seen causing problems with non-conforming parts. Up until now, these driftshave been counter-acted based on the knowledge and experience of the press line operators.This experience-based process control will however become more troublesome in the future asrecycled material grades will undoubtedly present […]

Abstract Within the automotive industry, there is an increasing demand for a paradigmshift in terms of which materials are used for the manufacturing of the automotive body. Globalclimate goals are forcing a rapid adaption of new, advanced, sustainable material grades suchas the fossil free steels and materials containing higher scrap content. With the introduction ofthese […]

ABSTRACT In sheet metal stamping, the occurrence of strain localization in a deformed sheet is considered a failure. As so, sheet metal’s formability is conventionally evaluated using the Forming Limit Diagram (FLD), which separates the principal strain space into safety and unsafety regions by a Forming Limit Curve (FLC). This study presents an evaluation method […]

Abstract As new and more advanced sheet metal materials are introduced to the market, more accurate techniques for determination of failure limits are needed. One area that needs attention is edge formability, where the ISO-16630 standardized Hole Expansion Test currently is used to express this through the Hole Expansion Ratio. Over the years, this standard […]
