“…Such coupling effect can be frequently seen in the hard body impact [34]. When compared with the impact motion of the PVB LG panel that has previously been reported [20], the impactor acceleration for the SGP LG panel exhibits more rapid variation so that its first plateau ends at nearly 21.2 ms, while that of PVB LG ends at later than 60 ms. The peak impactor displacement of the PVB LG is approximately 90 mm.…”

“…Liu [20] carried out a set of tests on real car windscreens under headform impact at velocities ranging from 6.6 m•s -1 to 11.2 m•s -1 and at impact angles ranging from 60° to 90°. The evaluation of the peak contact force and head injury criterion (HIC) demonstrated the correlation between the PVB interlayer properties and the energy absorption capability of the windscreen.…”

“…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).…”

“…The superior damage-tolerance of laminated glass compared to its monolithic counterpart is the reason for their widespread use as safety glasses in the automotive (Liu et al, 2016;Yuan et al, 2017b) and civil (Zhang et al, 2013;Yuan et al, 2017a) industries. Laminated glass typically consists of two brittle glass layers bonded by a polymeric interface (or interlayer) that has excellent optical and adhesive properties, such as SentryGlas ® Plus (SGP).…”

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.

“…For instance, Bois et al [41] simulate an impact of a sphere into a glass plate using an element delete method. Liu et al [22] adopted EDM to investigate the energy absorption process of windshield under different impact speeds and angles. Extended finite element method (XFEM) [23][24][25][26] is also applied to the fracture simulation of soda-lime glass.…”

In this paper, rate-dependent cohesive zone model was established to numerical simulate the fracture process of soda-lime glass under impact loading. Soda-lime glass is widely used in architecture and automobile industry due to its transparency. To improve the accuracy of fracture simulation of soda-lime glass under impact loading, strain rate effect was taken into consideration and a rate-dependent cohesive zone model was established. Tensile-shear mixed mode fracture was also taken account. The rate-dependent cohesive zone model was implemented in the commercial finite element code ABAQUS/Explicit with the user subroutine VUMAT. The fracture behavior of a monolithic glass plate impacted by a hemispherical impactor was simulated. The simulation results demonstrated that the rate-dependent cohesive zone model is more suitable to describe the impact failure characteristics of a monolithic glass plate, compared to cohesive zone model without consideration of strain rate. Moreover, the effect of the strain rate sensitivity coefficient C, the mesh size of glass plate and the impact velocity on the fracture characteristics were studied.
