Geometric correction processes contribute to zero-defect manufacturing for improved
product quality. Thin-walled metallic components are widely used in numerous applications …

Springback, wrinkling, and thinning typically occur during the stamping of thin-walled
semicircular shells with bending angle. These defects cause poor forming accuracy of …

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

Accurately predicting the amount of springback has always been a prior focus in metal
forming industry, particularly for creep age forming (CAF), for its significant effect on tool cost …

To satisfy the higher accuracy requirement in the microforming of thin-walled structures, the
springback behavior under miniaturizing dimensions need to be accurately predicted and …

Rotary bending springback (RBS) is a key problem in the bar roll straightening process.
Existing analytical methods ignore strain paths, and simplify RBS to in-plane reciprocating …

The competition among sheet-metal-forming manufacturers in recent years has become
more severe. Many manufacturers have survived by cutting their production costs …

Springback is a stress-driven phenomenon during unloading, so the stress behavior during
unloading is of great significance for exploring and understanding springback. However, the …

Sheet metal shaping for advanced high strength (AHS) steel sheets is commonly utilized in
the manufacturing of automobile components. This helps to decrease the weight of new …

During the cold-bending process, the tooling suffers considerable damage due to excess
pressure. This also causes the machines to break down, causing problems in the precision …
