“…The material properties of the soda-lime glass and SGP are listed in Table 1. Whilst glass can generally be considered to be linear elastic and strain-rate insensitive (Liu et al, 2016;Xu et al, 2017), by contrast, SGP exhibits non-linear elasto-plastic response and is highly strain-rate dependent (Bennison et al, 2005;Zhang et al, 2015). In general, SGP becomes less ductile with increasing strain rate; for example, its failure strain reduces from about 400% under quasi-static loading rate to about 150% at a strain rate of 2000 s ≠1 (Zhang et al, 2015).…”

“…Even after cracks have permeated both brittle glass layers (or plies) in the laminated glass, it is still able to o er protection to the target space ahead from penetration by foreign objects due to the ductile interlayer, which also serves to bind the majority of the glass splinters prior to its rupture. There are numerous recent studies examining the in-plane cracking of individual glass plies in laminated glass; for example, by Chen et al (2013Chen et al ( , 2014; Xu et al (2017Xu et al ( , 2016. Instead, this study seeks to further elucidate the conditions (specifically on interface location and impact kinetic energy of a projectile) that a ects crack growth across the interface in SGP laminated glass through an optical caustic method, which allows the concurrent measurements of dynamic stress intensity factor and crack path.…”

The damage mode (crack arrest or bifurcation) that develops in SentryGlas ® Plus (SGP) laminated glass under dynamic impact loading is investigated experimentally in this paper. An optical caustic method is employed-which allows simultaneous measurements of the spatial and temporal evolution of crack paths and the dynamic stress intensity factor at the crack tip(s)-to elucidate the e ects of interface location and impact kinetic energy upon the fracture morphology, crack propagation velocity and the dynamic stress intensity factor in SENB (single-edge notch bend) test specimens loaded in three-point bending by a dropweight impact system. Results reveal that there is a critical distance, between the interface and pre-crack tip, below which the propagating mode-I crack is arrested by the interface; otherwise, bifurcated mixed-mode cracks will always appear in the impacted glass layer. A maximum dynamic stress intensity factor criterion is shown to be capable of predicting whether bifurcated mixed-mode cracks would appear in the aforesaid.

Impact Fracture and Fragmentation of Glass via the 3D Combined Finite-Discrete Element Method

et al. 2021

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.
