Wrinkling Behavior Of Laminated Steel Sheets

The wrinkling behavior of laminated steel sheet was investigated 11.

Wrinkling behavior of laminated steel sheets.

For example the clad sheet such as damping steel sheet in which plastics are sandwiched with steels is now in practical use. It has been observed that the laminated sheets are prone to wrinkling during stamping processes. Laminated steel sheets sandwiched with a polymer core are increasingly used for automotive applications to improve vehicle u27s vibration damping performance without adding additional weight. It has been observed that the laminated sheets are prone to wrinkling during stamping processes.

Thin metal sheets are increasingly used for different purposes in automotive and aerospace industry. These sheets are prone to wrinkling during forming which is a major defect. Due to the significant difference in material properties between the polymer core and the skin steel fem prediction of the occurrence the location and the shapes of wrinkles in the forming of laminated sheets is still a great challenge. It has been observed that the laminated sheets are prone to wrinkling during stamping processes.

In addition they conducted rectangular panel forming tests and compared the wrinkling resistance of monolithic sheets and laminated sheets as. A steel polymer steel three layer laminate is a new composite sheet which recently starts to be used in automobile parts and panels for the purpose of vibration damping and weight reduction. Due to the significant difference in material properties between the polymer core and the skin steel fem. Its initiation may be due to material properties geometric constraints and stress applied.
