Abstract

Low velocity drop ball impact response of monolithic and laminated glasses was studied using analytical and Finite Element (FE) methods. Material linear elastic and damage responses were considered throughout the numerical analysis. The performance of monolithic and laminated plate glasses subjected to the impact loads in normal and oblique angles was thoroughly examined.
In this study, the verification of the analytical and numerical models has been conducted by using one of the previous investigation results. The adopted analytical models include the spring-mass model, energy balance model and wave propagation method for the infinite thick plates, respectively. The results from the wave propagation analytical method found a good agreement with open literature results and it was recommended for future impact predictions. The prediction results obtained include the time histories for impactor-glasses contact force, displacement and velocity during impact under various parameters, such as impact velocity, impact mass and glass plate and PVB interlayer thicknesses. A three-dimensional (3D) finite element method (FEM) is used to model and simulate impact response of both monolithic and laminated glass. The finite element (FE) commercial software package ABAQUS was used in the numerical simulation. The numerical model geometry obtained as a symmetric and full section, which incorporated 8-nodes linear solid (Brick) elements with reduce integration method.
