Journal ArticleDOI
High speed tensile test of steel sheets for the stress-strain curve at the intermediate strain rate
Hoon Huh,J. H. Lim,S. H. Park +2 more
TL;DR: In this article, a servo-hydraulic type high speed tensile testing machine was used to obtain stress-strain curves of mild steel and advanced high strength steels at strain rates ranged from 1/sec to 200/sec.
Journal ArticleDOI
Prediction of fracture in hub-hole expanding process using a new ductile fracture criterion
TL;DR: In this article, a modified ductile fracture criterion is proposed to consider the deformation characteristics of a material accurately in a hole expansion process, which can predict the fracture mode and the hole expanding ratio accurately.

Tubular Torsion Beam for Rear Suspensions of Vehicles and Manufacturing Method Thereof
TL;DR: In this article, a tubular torsion beam for rear suspensions of vehicles is presented, which is produced according to a more durable design capable of improving roll stiffness and roll strength of the beam.
Journal ArticleDOI
Simulation-based prediction model of the draw-bead restraining force and its application to sheet metal forming process
TL;DR: In this article, a simulation-based prediction model of the circular draw-bead is developed using the Box-Behnken design with selected shape parameters such as the bead height, the shoulder radius and the sheet thickness.
Journal ArticleDOI
Formability of the Steel Sheet at the Intermediate Strain Rate
TL;DR: In this article, the tensile elongation has been obtained from various steel sheets for an auto-body at the intermediate strain rate, and the experimental results demonstrate that the elongation does not decrease as the strain rate increases.
