Prestretched laminates

Please login with a confirmed email address before reporting spam

Hello,

We are trying to find out the topology of a two-layer laminate.

Both base and top layers are polymers, with similar Poisson's ratio.

The top polymer layer is deposited on the prestressed base (by 5% strain in radius).

After releasing the stress on the base, the top layer is expected to buckle (provided the interlayer adhesion is sufficient).

Is there a way or similar model to solve this problem and see how the topology of the top layer?

Thank you very much in advance!

Sincerely,
Lanlin
