Wrinkling Behavior Of Laminated Steel Sheets

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.

Wrinkling behavior of laminated steel sheets.

It has been observed that the laminated sheets are prone to wrinkling during stamping processes. Its initiation may be due to material properties geometric constraints and stress applied. For example the clad sheet such as damping steel sheet in which plastics are sandwiched with steels is now in practical use. Studied the wrinkling behavior of laminated steel sheets sandwiched with a polymer core and verified their fem results using experimental data provided by youshida and a wedge strip testing.

Due to the significant difference in material properties between the polymer core and the skin steel fem. 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. 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.

Wrinkles are formed due to non uniform compressive stresses resulting from multi axial stretching of materials. Laminated steel sheets sandwiched with a polymer core are increasingly used for automotive applications to improve vehicle s vibration damping performance without adding additional weight. In addition they conducted rectangular panel forming tests and compared the wrinkling resistance of monolithic sheets and laminated sheets as. The wrinkling behavior of laminated steel sheet was investigated 11.
