GS&E journal > Adhesion Rupture in Laminated Glass: Influence of Interfacial Adhesion on the Energy Dissipation Mechanisms

In laminated glass under impact, most of the energy dissipation occurs in the coupled delamination and deformation of the polymer interlayer. The strong dependency of these mechanisms on interlayer nature, on loading rate and on temperature is known: however, the effect of the interfacial adhesion...

description	In laminated glass under impact, most of the energy dissipation occurs in the coupled delamination and deformation of the polymer interlayer. The strong dependency of these mechanisms on interlayer nature, on loading rate and on temperature is known: however, the effect of the interfacial adhesion is unexplored.

We show that changing adhesion mostly affects dissipation close to the delamination front, while dissipation in the volume of the PVB interlayer seems unaffected, which we attribute to the competition between the changes in both strain and strain rate in the viscoelastic interlayer.
