Abstract
This paper investigates the dynamic responses of nanomaterial enhanced laminated glass panel under impact loadings. In the study, numerical simulation of a rigid ball impacting on the laminated glass panel is performed using an explicit finite element code, LS-DYNA3D. The parameters that have been studied are impact velocity, ball size and adhesion strength. It is found that the severest damage to the glass does not occur at the highest impact velocity but at the critical velocity of penetration. Moreover, increasing the ball size will result in a significant reduction of energy absorption by the polymer interlayer. On the other hand, increasing the tensile adhesion strength between the glass and polymer layers can effectively reduce the possibility of delamination. The preliminary simulation results have provided information that is useful to effectively understand the dynamic performance of the new laminated glass panel under impact.
