摘要

The fracture behaviour of glass under hard body impact is simulated using the combined finite-discrete element method with a finite element incorporated into the discrete elements. A Mode I fracture model is employed and proven to be successful in modelling the crack initiation and tracking the crack propagation in glass. Cone, flexural and punching damages are obtained thus qualitatively verified the glass fracture model. A parametric study on tensile strength, fracture energy and impact velocity further examines the breakage behaviour of glass, demonstrating the applicability of this computational technique for the analysis of glass impact mechanism.
