“…Furthermore, the models are too cumbersome to apply in practical applications such as designing of glass–bolted joints. Alternatively, the concept of eigenstrains, where the effects of the complex non-linear cooling process of glass are approximated with a linear elastic approach, 20,21 was used in the present study to incorporate the effects of residual stresses in glass.…”

“…The measured surface residual stress values 9 of 5 and 30 MPa in annealed and HS glass, respectively, were used in the FE models to determine the results shown in Figure 5. The eigenstrains technique can appropriately model the full 3D residual stress distribution in a glass specimen even if there is an up to ±10% error in the SCALP measurements 21 (note: the manufacturer expected errors in SCALP measurements are much smaller 22 ). The results show that the spatial distribution of σ rs_xx is not uniform on xy -plane in the vicinity of the hole.…”

“…The eigenstrains method of incorporating the effects of the full 3D residual stress distribution in glass, which was previously developed by the research group led by the author of the present paper, requires only the knowledge of the surface residual stress of the given glass in order to model the full 3D residual stress distribution. 21 The surface residual stress value of a given glass is usually available from the glass manufacturer or can be measured using a scattered-light-polariscope (SCALP). 22 The development and applications of the eigenstrains-based model are published elsewhere, 21 and therefore, the details are not repeated in the present paper.…”

Since this technique of modelling of residual stress in glass explicitly incorporates the geometry, material behaviour and boundary conditions of a given glass specimen, the method enables accurately modelling the residual stress distributions in both flat glass panels and complex geometries such as drilled holes in glass.…”

This paper presents the development of finite element (FE)-based computational models that can be used for predicting the failure load of GFRP-reinforced annealed and heat-strengthened glass–bolted joints. Stress analysis of a single-bolt, single-glass-piece case was first carried out in order to develop the computational models and to establish an appropriate failure criterion for the GFRP-reinforced glass–bolted joints. The computational models were then calibrated against the experimental results reported in a previous experimental study involving reference and reinforced double-lap tension joint test specimens. The paper shows that the failure of both reference and reinforced glass–bolted joints can be predicted using the maximum principal-tensile-stress-based failure of glass. The results also confirm that the use of adhesively bonded GFRP reinforcement has potential to increase the load capacity of the reinforced glass–bolted joints compared to the reference glass–bolted joints.

The mechanical and safety-relevant properties of tempered architectural glass are tested using destructive bending strength and fracture pattern tests. The edge stress provides essential information on the quality of the tempering process and can, therefore, be used to ensure quality characteristics. The paper shows that the current valid evaluation method for edge stress, according to ASTM C 1279-09, is unsuitable for architectural glass. The chamfer which is required for tempered glass by the European standards for tempered glass prevents the direct measurement of retardation and edge stress. Therefore, an extrapolation of the retardation curve towards the edge is necessary. The paper compares fitting functions of different polynomial degrees to determine and assess the edge stress. The objective is to develop a proper evaluation method of edge stress for quality control in the latest inline measurement systems which can be applied to replace operator-dependent measuring devices. The study presents appropriate methods and evaluates them through experimental investigations using the phase shift technique and multiple wavelength photoelasticity.
