Abstract

This paper deals with the calculation of dynamic response of curved laminated glass panels under blast loads by means of theoretical analyses and finite element simulation.In the investigation,first,the theoretical calculation methods of dynamic responses of flat laminated glass panels with clamped boundary are deduced,finding that the PVB elastic modulus greatly influences the accuracy of theoretical calculation.Then,the dynamic responses of curved laminated glass panels under blast loads are discussed,finding that there are two stable coefficients of curved panels ( CCP) ,which may provide a simplified method for the dynamic response calculation of curved laminated glass panels,that is,to obtain the maximum deflection and principal stress of curved laminated glass panels by multiplying the corresponding values of flat laminated glass panels in the same size with some coefficients.Meanwhile,the influences of geometric parameters of the curved laminated glass panels on the CCP are quantitatively analyzed,and reliable empirical formulas are fitted.This research provides a simple and practical calculation method for estimating the dynamic responses of curved laminated glass panels.
