•The effect of interlayer type/thickness on impact fracture of LG is reported.•MD, MES, and MPES are related with fragment size and amount of damage.•Fracture of all the LG samples is described.•FE analysis is conducted to support experimental results.•The average size of the fragment for LG-PVB is lower than the LG-EVA. The present work includes fracture and adhesion testing of laminated glasses (LGs) with different inter-layers (Polyvinyl butyral (PVB), Ethyl vinyl acetate (EVA)) and their different critical thicknesses (0.38, 0.76, 1.52 mm) following the IS 2553. The fracture pattern of each type of LG sample is discussed. The finite element (FE) analysis is conducted to obtain the total deformation, equivalent stress and equivalent strain of LG samples. The effect of inter-later type and thickness on fracture pattern of LG samples, fragment size, maximum deformation (MD), maximum equivalent stress (MES), maximum equivalent principal strain (MPES) is also discussed. The statistical analysis is conducted for the validation of experimental results. The failure processes and damage characteristics of LG can be predicted /explained collectively from the results of the experimentation and simulation. The results of the present work can be utilized by the design engineers while selecting LG for structural and automotive applications.
