On the Impact Fracture Simulations of Automotive Laminated Glass

Abstract

In this work, we review three kinds of numerical algorithms, namely the discrete element method (DEM), the coupling discrete element and finite element method (DEM/FEM) and the cohesive zone model (CZM), for the impact fracture simulations of automotive laminated glass. Based on the non-continuum theory, the DEM is capable of modeling the impact fracture phenomenon. However, this method is very time-consuming. To remedy this shortcoming, we have been devoted to combining the discrete element method and the finite element method. Another notable work is to simulate the impact fracture behaviors by using the CZM. Some future works concerning this research aspect are also presented.
