Detailed experimental and numerical analysis of a cylindrical cup deep drawing: Pros and cons of using solid-shell elements [PDF]

open access: yesInternational Journal of Material Forming, 2017
The Swift test was originally proposed as a formability test to reproduce the conditions observed in deep drawing operations. This test consists on forming a cylindrical cup from a circular blank, using a flat bottom cylindrical punch and has been extensively studied using both analytical and numerical methods.

STRAIGHTENING OF LOW-RIGID CYLINDRICAL DETAILS. PART 2. STRESSED STATE OF CYLINDRICAL BILLETS AT TRANSVERSE CHEESING BY FLAT PLATES

open access: yesIzvestiya. Ferrous Metallurgy, 2019
To restore the shape of curved low-rigid cylindrical details such as shafts and axles, bending straightening under distributed loading is proposed, followed by hardening of the billet using surface plastic deformation based on transverse cheesing of it by flat plates.
