Failure analysis of tempered glass structures with pin-loaded joints

Abstract

Pin-loaded joints are frequently used to assemble tempered glass plates. To prevent such structures from fracture, a holed glass plate is reinforced by a steel ring and glued to it through a soft resin layer. The present work first models and identifies the mechanical behaviour of the constituent materials and then analyzes the failure process of tempered glass structures with pin-loaded joints, in which unilateral contact, friction, damage and residual stresses are involved. The numerical results obtained by the finite element method are in good agreement with the experimental ones issuing from the real size test.

Experimental results of mechanical, adhesive, and laminated connections for laminated glass elements – A review

“…Double-lap shear [ 6,[8][9][10] Clamp [ 11] -Glass cutting, drilling and thermal strengthening is not necessary.…”

“…Therefore, when only one of the substrates was glass, the load was mainly applied on the other material (steel, GFRP, etc.) [ 6,9,15,20,26]. In glass-to-glass connections, compressive loadings were preferably carried out [ 15], and clamps with intermediate material were used to apply tensile loads [ 14].…”

“…To et al [ 9] carried out an experimental campaign aiming to determine the strength of bolted joints with tempered glass under in-plane loading. Between the steel bolt and the glass borehole, three concentric rings were placed: an inner cooper ring, an intermediate stainless steel ring, and an outer adhesive resin (mixture of epoxy resin and hardener) ring.…”

“…Watson et al [ 10] carried out a tensile double-lap shear test similar to the one performed by To et al [ 9]. Their goal was to determine the critical flaw size at which cracks propagate under a certain tensile load.…”

“…To vd., pim bağlantılı temperlenmiş cam yapı elemanlarında meydana gelen hasarı deneysel ve nümerik metotlarla incelemişlerdir. Çalışma sonucunda, sonlu elemanlar metodu ile elde ettikleri nümerik sonuçlar ile gerçek boyutta test ettikleri deneysel sonuçların birbiriyle uyum içinde olduğu görülmüştür [10]. Gerdun vd.…”
