This study derives a uniaxial tensile flow from spherical indentation data using an artificial
neural network (ANN) combined with finite element (FE) analysis. The feasibility of the FE …

The determination of residual stress distributions in cold-formed members is revisited
considering both experimental and numerical methodologies. Destructive, semi-destructive …

The improvement of lightweight and safety is the development requirement of automobile
parts. Therefore, the demand of thin-walled parts with ultra-high strength is more urgent …

The metal forming process often involves multiple reciprocating bending springback
problems. The springback prediction of reciprocating bending is more difficult than that of …

Abstract Ultra High-Strength steels (UHSS) is increasingly used in automotive industry to
reduce weight and improve consumers' safety. However, prediction of springback in cold roll …

With the widely use of high-strength steel sheets in the automotive industry, the twist
springback phenomenon of the steel sheets under multi-step forming conditions has …

In this paper, the uniaxial loading–unloading–reloading (LUR) tensile test was conducted to
determine the elastic modulus depending on the plastic pre-strain. To obtain the material …

Three-dimensional free-bending is a new and an advanced forming technology to
manufacture the complex metal hollow components with continuously varying radius. In this …

Background The conventional isotropic elastic model neglects the anisotropy of sheet
metals' elastic modulus, leading to inevitable errors in springback prediction. Objective …

Usage of high-strength steels with limited bendability in conventional air bending is not
obvious due to the deformation limits of these materials. An attractive solution for …
