Forming

EWI has recently developed a new technique to obtain improved accuracy in material flow stress for modeling metal forming processes. The method uses the hydraulic bulge test (HBT) and digital image correlation (DIC) analysis and applies the plastic work equivalency principle to determine an optimal arc length for the for calculation of a biaxial flow...

Emerging materials such as high-strength aluminum alloys, advanced high-strength steels (AHSS), and GEN3 steel have been increasingly applied in sheet metal forming components. These materials are known to have unique elastic and plastic material behaviors which create new challenges for engineers and designers. One of the behaviors is springback. Springback challenges include difficulties predicting, controlling,...

Updated Formability Test Methods, an EWI technical webinar, was presented by Engineering Group Leader Laura Zoller and Project Engineer Amir Asgharzadeh on May 3rd.
