“…SG foils are rather rigid at room temperature. In literature, the bulk SentryGlas material has been investigated under uniaxial stress state by several authors (Bennison 2005;Meissner and Sackmann 2006;Belis 2009;Biolzi et al 2010;Puller et al 2011;Schneider 2012;Kuntsche and Schneider 2014). Tests were performed at room temperature and different displacement rates.…”

An innovative type of connections for glass components, called laminated connections, has been developed in the last years. Two materials have been used for laminated connections: the transparent ionomer SentryGlas (SG) from Kuraray (former Dupont) and the Transparent Structural Silicon Adhesive (TSSA) from Dow Corning. In this paper, the mechanical behaviour of SG and TSSA bulk materials is studied under uniaxial tensile stress condition. The effects of strain rate and temperature variations are investigated. Particular attention is paid (i) to the study of these polymers in cured condition and (ii) to the computation of true stress and strain field during the tests. Firstly, it is observed that the mechanical behaviour of both SG and TSSA are temperature and strain rate dependent. These effects are quantitatively determined in the paper. Secondly, two additional phenomena are observed. For TSSA, it is observed that the material goes from fully transparent to white colour, exhibiting the so-called whitening phenomenon. For SG, instead, it is observed that the strain field distribution is dependent on the temperature. More specifically, the material exhibits a non-uniform strain field distribution due to the occurring of the necking phenomenon. Measurements along the specimens, using Digital Image Correlation techniques, showed that the localized strain propagates over the full specimen length, resulting in a cold-drawing phenomenon. Finally, it is also shown that engineering and true stress-strain definition exhibits large deviation indicating that the finite deformation theory should be used for the computation of the stress-strain curves to be implemented in numerical modelling.

“…Such a displacement is related to the radial displacement by a relationship of the form (4. 26) and, consequently, the explicit expression for the radial displacement v 0 (q). Whenever the layered (G ¼ 0) or the monolithic (G / ∞) limits are attained, the solutions read respectively Fig.…”

“…Thus, the flexural performance is intermediate between the two borderline cases [18,19] of monolithic limit (shear-rigid bonding of the glass plies) and layered limit (free-sliding glass plies). Since stress and strain are much lower in the monolithic than in the layered limit, to avoid redundant design a large number of theoretical studies have been performed [20e25], corroborated by a wealth of experimental activity [26,14,27,28]. Several practical methods to readily calculate the response of laminated glass structures, such as those by Refs.…”

“…The recent experimental investigations by the author were considered [15][16][17] (to validate the analytical and the numerical model proposed here. Unfortunately, because none were available in the literature in a complete form, it was not possible to add any other experimental investigation on the flexural behaviour of beams with T or I cross-section shapes (Ply, 1988).…”

Abstract-Flexural behavior of laminated glass beams was numerically predicted through an open source finite element code; a cohesive-frictional behaviour of the adhesive and the brittle fracture of the glass were implemented though adequate constitutive laws. Both the processes of de-bonding of interlayer and the failure of glass panels can be captured by a refined finite element analysis. Based on the elastic theory, simple analytical expressions are utilized for the prediction of composite glass beams, including the extreme cases of full composite and layered behaviour. Cases of study refer to glass composite beams having T or I cross-section shapes. Beams consist of laminated glass (LG) flanges and LG web that is assembled together by different kinds of polymer adhesive (semi-rigid i.e., silicones, modified silicones and polyurethanes and rigid i.e., epoxy resins, acrylics). Experimental data given in the literature was utilized to show the effectiveness of numerical model to reproduce experimental results, and to show the effectiveness of the proposed elastic model for preliminary beams in flexure design.
