(2008)Challenging glass : conference on architectural and structural applications of glass.p.459-467 Mark abstract Firstly is introduced what the post-breakage behaviour of laminated safety glass is, and why it's important to can model it for designing structural glass elements. A general description of post-breakage behaviour and the different possible mechanisms leading to failure are presented. We then focus on the mechanical properties of the interlayer material, more specifically in the perspective to model its behaviour at large strain up to break. Typical results of standard uniaxial tensile tests on SGP samples (SentryGlas (R) Plus, interlayer of DuPont de Nemours) are shortly presented, and we then explain why those are insufficient to calibrate numeric material models to use in finite elements softwares. Finally perspectives for further experimental investigation with aiming to calibrate material models are presented.
