The effect of edge condition and edge failure is significant while measuring the flexural strength of laminated glass (LG), thus, the biaxial tests such as ring-on-ring (ROR), ball-on-three-ball, ball-on-ring, and piston-on-ring are preferred over uniaxial tests such as three-point or four-point bending test. In the present work, the effect of inter-layer type (polyvinyl butyral (PVB) and ethyl vinyl acetate (EVA)) and inter-layer thicknesses (0.38, 0.76, 1.52 mm) on the flexural strength of LGs is reported. The flexural strength is measured using ROR test following the ASTM C1499-15. It is found that LG-EVA is stiffer and has the higher load-bearing capacity than the LG-PVB. An increment in the average load-bearing capacity is reported with an increment in inter-layer thickness in both LG-EVA (more prominent) and LG-PVB. The statistical analysis has confirmed the soundness of experimental results and the reliability of flexural strength of LG on the inter-layer type and thickness. Further, a finite element (FE) model is constituted for observing the total displacements (an indicator of the severity of fracture) observed by the LGs at their load-bearing capacity. The FE analysis has predicted the fracture pattern observed by the LG samples satisfactorily.
