There are various processes practiced in a market for manufacturing axisymmetrical cup
with significant forming depth among which deep drawing process is most prompt. The deep …

The precision forming of thin-walled components has been urgently needed in aviation and
aerospace field. However, the wrinkling induced by the compressive instability is one of the …

The high-strength steel sheets currently used in the automotive industry are prone to non-
traditional behaviour during forming, being wrinkling and springback two of the most …

An apparatus was designed, simulated, optimized, and constructed to enable the large-
strain, continuous tension/compression testing of sheet materials at elevated temperature …

Wrinkling in unsupported region is a worthy problem to be solved in sheet metal forming
process. Sheet hydroforming is advantageous in the prevention of unsupported wrinkles …

Wrinkling on the unsupported area of some deep drawn shells with curved surface and thin
thickness is extremely hard to control. Sheet hydroforming process is of concern to eliminate …

Forming limit diagrams (FLDs) are extensively used in industries, particularly the auto
industry. The establishment of these diagrams using a predictive approach can lead to …

Wrinkling in sidewall for curved surface part is a big obstacle by traditional deep drawing,
and which severely influence the surface quality and service performance of part. The pre …

Aiming at the problems of complex processing technology, uneven deformation, and poor
forming accuracy of multi-curvature positive Gaussian slewing egg-shaped shells, it is …

The recent trend to reduce the thickness of metallic sheets used in forming processes
strongly increases the likelihood of the occurrence of wrinkling. Thus, in order to obtain …
