“…The SSTF has proven to be a reliable alternative to explosive detonations, and enables a planar pressure loading to plated specimens. A detailed description of the SSTF and its performance can be found in [14]; however, a short description is given herein for completeness. The purpose of the SSTF is to subject specimens to a pressure history similar to that from a far-field blast event within a controlled laboratory environment.…”

“…To estimate the reflected pressure on the tested glass plates, two piezoelectric pressure sensors were placed 245 mm and 345 mm upstream the plate (see Figure 6a). By assuming constant velocity of the blast wave between the furthest sensor and the plate, the reflected pressure could be determined [14]. The pressure measurements were logged with a frequency of both 500 kHz and 24 kHz.…”

“…This includes quasistatic four-point bending tests on relatively small glass specimens, and quasi-static and dynamic lateral pressure tests on larger glass plates. The dynamic pressure tests involve subjecting the glass plates to a blast pressure in the SIMLab Shock Tube Facility (SSTF) [14], while the quasi-static pressure tests employ a slowly increasing water pressure. The experimental work shows that the 55 fracture strength of glass depends on both size and loading condition, and has a great variation within the same test setup.…”

In recent years, a considerable number of studies has been carried out to analyse the behaviour of laminated glass plates under blast loading by the use of the finite element method. This has proven to be quite challenging, as the response of the laminated glass is complex. The fracture strength of the glass layers govern much of the total response; however, a limited effort is often made to selecting this value in the analyses. The current work aims to identify the probabilistic fracture strength of the glass alone as a function of its geometry, boundary conditions and loading situation by the use of a newly proposed strength prediction model. It should be noted that the current study focuses on the initiation of fracture in glass plates, and no effort has been put into the description of crack propagation. To facilitate the validation of the model, three different experimental test series were carried out on annealed float glass. This included quasi-static four point bending tests on relatively small glass specimens, and quasi-static and blast pressure tests on larger glass plates. The experimental work demonstrated that the fracture strength of glass exhibits a large scatter within the same test setup. It also revealed that the fracture strength and its scatter were dependent on the geometry, and the boundary and loading conditions. The strength prediction model was able to successfully capture many of the trends observed in the quasi-static tests. Regarding the blast tests, the model was able to reproduce the experimental results reasonably well.

Three different experimental set-ups were employed in the investigation of the fracture strength of annealed float glass. These included four-point bending tests on three different specimen sizes, and quasi-static and dynamic pressure tests. The latter tests were conducted in a shock tube, i.e., a device that produces pressure loadings similar to that from a far-field blast event. The experimental work demonstrated that the fracture strength of glass varies largely within the same test set-up. It also revealed that the fracture strength and its scatter are dependent on the size of the specimen, the boundary conditions and the loading situation. By employing a newly proposed strength prediction model, which relies on the physical fracture behaviour of glass, the trends observed in the experiments were correctly recreated.
