This paper reviews the most recent models for description of the anisotropic plastic behavior
and formability of sheet metals. After a brief review of classic isotropic yield functions, recent …

Superalloy ultrathin sheets have high strength, outstanding oxidation resistance, corrosion
resistance and fatigue performance, and its thin-walled components occupy a considerable …

In this study, the performance of conventional and advanced constitutive models to the
prediction of springback for ultra-high strength steel was assessed. The elasto-plastic …

The unloading process of hot-deformed aluminum alloys exhibits obvious strain rate-and
deformation temperature-dependent nonlinearity and the springback is generated by …

The constitutive equations for the irreversible mechanical phenomena, eg the plastic
deformation and the sliding between solids with the friction have been studied over the …

Electrically-assisted (EA) forming is an effective method to improve forming quality of sheet
metal. In order to reveal the effects of current on material flow behavior under complex strain …

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

Multiple bending faces more challenges in accurate springback prediction for difficult-to-form
metals such as aluminum alloys and high-strength steels. This is attributed to stress …

Unloading-reloading behavior is of crucial importance in multi-pass forming of metal
materials, the nonlinear of which creates challenges for the analysis of springback and …

This study investigated the elastic recovery phenomenon with elapsed time and heat
treatment after the plastic deformation of automotive steel sheets. A conventional uniaxial …
