Experimental study on the gradual fracture of layers in multi-layer laminated glass plates under low-velocity impact

“…Similar conclusion was reached by Overend et al in [4] for laminated glass beams under quasi-static bending, where the post-fracture bearing capacity of tested multi-layer laminated glass units was significant and also exceeded in some cases the strength at first fracture. In [39], the authors also reported an improvement in post-breakage stiffness of samples with heat strengthened glass layers compared to fully tempered glass layers due to their beneficial fragmentation pattern. Further, experimental results in [40] confirmed that the annealed glass plies provided the highest resistance in the post-breakage phase.…”

“…Limited amount of works can also be found for the impact response of multi-layer laminated glass in the last decade, identifying the critical impact load for laminated glass panels with a few broken glass layers. Wang et al pointed out, in their experimental study on lowvelocity impact resistance of multi-layer glass panels [39], that the peak impact force at the second breakage was in some cases larger than that at the first breakage. Similar conclusion was reached by Overend et al in [4] for laminated glass beams under quasi-static bending, where the post-fracture bearing capacity of tested multi-layer laminated glass units was significant and also exceeded in some cases the strength at first fracture.…”

Influence of boundary conditions on the behavior of laminated glass curved beam with delamination effect: An experimental and numerical investigation

“…In the 2000's, theoretical [ [20] , [21] , [22] , [23] , [24] , [25] , [26] ], numerical [ [28] , [29] , [30] , [31] , [32] ] and experimental [ [33] , [34] , [35] , [36] ] researches on the actual behavior of laminated glass further enhaced. Researches showed that structural behavior of laminated glass stands among two limiting cases which are layered and monolithic cases [ 2 , 7 , 8 , 19 ]…”

Local bridging effect of fractured laminated glass with EVA based hybrid interlayers under weathering actions

“…Numerical attempts using combined Voronoi tessellation and finite-discrete element method were also carried out by Wang et al to investigate the influence of fracture pattern on the stiffness and resistance of fractured tempered glass laminates [13] and beam [14]. The findings so far reveal that the residual resistance of fractured glass is also highly related to the interlayer and adhesion properties [15]. For example, a stiffer interlayer or higher adhesion level will limit the volume expansion of tempered glass fragments at breakage point and hence facilitate integrity of glass layer.…”
