A driving technical concern for the automobile industry is their assurance that developed windshield products meet Federal safety standards. Besides conducting innumerable glass breakage experiments, product developers also have the option of utilizing numerical approaches that can provide further insight into glass impact breakage, fracture, and fragmentation. The combined finite-discrete element method (FDEM) is one such tool and was used in this study to investigate 3D impact glass fracture processes. To enable this analysis, a generalized traction-separation model, which defines the constitutive relationship between the traction and separation in FDEM cohesive zone models, was introduced. The mechanical responses of a laminated glass and a glass plate under impact were then analyzed. For laminated glass, an impact fracture process was investigated and results were compared against corresponding experiments. Correspondingly, two glass plate impact fracture patterns, i.e., concentric fractures and radial fractures, were simulated. The results show that for both cases, FDEM simulated fracture processes and fracture patterns are in good agreement with the experimental observations. The work demonstrates that FDEM is an effective tool for modeling of fracture and fragmentation in glass.

Laminated glass which consists of two glass sheets connected to each other with PVB interlayer is used in many engineering applications for years. Despite the long history of the use of laminated glass in buildings there are serious problems about delamination of laminated glass units. This paper provides information about delamination issues of laminated glass plate structures. Delamination of laminated glass unit may be due to the thinning of PVB (Polyvinyl Butyral) interlayer or the folds which occur during the manufacturing process. Laminated glass behaves in a complex manner due to the effect of geometry that undergoes large deflection even under their own weight and the order difference between the elastic modulus of glass and interlayer. Because of the mentioned reasons large deflection analysis has to be performed in the determination of the effect of delamination on the strength of laminated glasses.

Experimental Findings

The structural performance of cantilevered laminated glass plates for different glass thicknesses and interlayers is considered in this paper. Heat-strengthened and tempered glass plies and two different interlayer films were utilized. The response of laminated glass specimens is then evaluated under low-velocity hard and semirigid impacts. Experimental findings were simulated and discussed by means of finite element analyses. In particular, this discussion includes the evaluation of the influence that the fixed edge clamping technique (number of clamps, their size, and their stiffness) has on the stress distribution in the specimens.

Laminated Panels

Laminated glass composites are structural glass members made by assembling thin laminated panels which are connected by structural adhesives called interlayer. Laminated glass composite is a safety and security glass which enables significant improvement in the post-breakage behaviour. The interlayer of laminated glass composites ensures the integrity of the glass by holding it together. In the field of modern and innovative architectural engineering, the applications of laminated glass composites are increasing due to its lighting, aesthetics and architectural advantages. This paper introduces the buckling and vibration characteristics of different laminated glass elements using ANSYS 16.2.
