Experimental investigation on the radial and circular crack propagation of PVB laminated glass subject to dynamic out-of-plane loading

Numerical Analysis of Impact Fracture of Laminated Glass - A Review

“…CZM is governed by a phenomenological traction-separation law and used frequently for performing failure analysis [74][75][76][77]. Chen et al [16] simulated the impact fracture of a LG under drop-weight impact. The common glass-ply crack patterns were captured in the simulations with a special designed FE meshes (Figure 4).…”

“…This functionality forces designers to use LG wherever there may be an injury risk due to glass fracture. A good no of theoretical studies [2][3][4][5][6][7][8], experimental studies [9][10][11][12][13][14][15][16][17][18][19][20][21][22] numerical studies [10,, LS DYNA and ABAQUS based studies [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] and discrete element (DE)/finite element (FE) based studies are reported to analyze impact failure of LG. The present work is focused on reviewing the numerical algorithms used to model the impact fracture of LG.…”

A three-dimensional computational framework for impact fracture analysis of automotive laminated glass

“…Up to now, both laboratory experiments and numerical simulations have been carried out to investigate the mechanical properties of laminated glass. Xu et al [3,4] conducted a series of experiments of laminated glass including quasi-static and dynamic tests. Specifically, the impact fracture behaviours such as the propagations of radial and circular cracks of laminated glass under dynamic loading were intensively studied by using a drop-weight device combined with a high-speed photography device [4].…”

Dynamic crack-interface interactions in SGP laminated glass: An experimental investigation

“…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.…”
