Dynamic torsion tests to characterize the thermo-viscoelastic properties of polymeric interlayers for laminated glass

Influence of interlayer properties on the blast performance of laminated glass panels

“…Different interlayer materials such as polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), ionoplasts and thermoplastic polyurethanes (TPU) are used in practice [3,4]. However, PVB is the most common interlayer material, which is mostly used in blast resistant glazing [5].…”

Flexural performance of hybrid beams made of glass and pultruded GFRP

“…Other studies were performed on the experimental analysis of the flexural, torsional buckling [10][11][12], of the interlayer behaviour [13,14] and also the viscoelastic response of the interlayer, which is time and temperature dependent [15][16][17]. In addition, given the fragility of the material, which depends mainly on the presence of micro-defects [18,19] and which does not allow one to disregard the possibility of breakage, many studies have focused on the post-fracture behaviour of glass beams [20][21][22][23][24][25].…”

Variationally-Based Effective Dynamic Thickness for Laminated Glass Beams

“…On the other hand, the nature of the polymer response is strongly frequency-dependent and also temperature-sensitive, e.g., [3], [4], or [5]. Its behavior is often described by a complex-valued dynamic shear modulus, see Figure 1.…”
