Abstract
For providing a basis for the safety design of windscreen glass, an out-plane impact test of PVB laminated glass panel is conducted on a drop-weight tester with a high-speed photography device. The dynamic process of crack growth is recoded and crack growth behavior is studied according to the velocity and acceleration curves of crack propagation obtained. Then on these bases, parametric experiments are performed to investigate the effects of impact energy and PVB film thickness on the characteristics of crack propagation. Finally, based on a great number of parametric experiment data, the macroscopic patterns of cracks are studied with probabilistic method. The results show that the growth velocity and acceleration of glass cracks and the occurrence frequentness of ring-shaped cracks all have significant correlation with impact energy and the thickness of PVB film.
