Abstract

The transparent armor and aircraft windshields are comprising of glass or transparent ceramic laminates joined with the polymeric interlayer. The interlayer thickness plays a vital role in improving the damage, impact, and wave propagation response of transparent laminates. The edge-on-impact simulations on monolithic ballistic soda-lime glass are performed first to investigate and verify the wave propagation using ANSYS/Autodyn. Secondly, to lessen the wave speed and damage area in the glass, the different thicknesses of PU interlayer were incorporated in the numerical model and analyzed. The delay time in wave arrival time as a function of interlayer thickness was estimated. Additionally, the influence of PU interlayer orientations and a number of layers (single & double) on longitudinal wave propagation and damage are also studied numerically and discussed.
