Surface mechanics and adhesion

Buckles, telephone cords and more

Thin films with strong compressive residual stresses and low adhesion may delaminate, forming buckles. Sometimes the mechanics of thin films conspires with the physics of adhesion to impart unexpected forms to these buckles. We investigate the contorted patterns of thin film buckles ;.

The lobes around this quasi-circular thin film buckle are induced by mode-mix dependent adhesion.
Impact on flat laminated glass

Dynamic rupture

Laminated glass is a sandwich of a thin PVB polymer film inside two glass plates. Paul Elzière investigates how PVB adheres and how laminated glass breaks.
