摘要：
A computational method in the impact fracture behavior simulation for laminated safety glass is presented using the discrete element (DE)/finite element (FE) surface-center coupling method and cohesive model. Automotive laminated glass is an important component of vehicle safety system, it consists of two glass sheets bonded with a polyvinyl butyral film. It is directly related to the safety of passengers and pedestrians. In-depth research and analysis of the failure mechanism of this glass is of great engineering significance. Drop hammer tests wire conducted to evaluate the simulation results. The DE/FE surface-center coupling method and cohesive model are shown to be capable of simulating the impact failure characteristics of laminated glass. The results would be instrumental for simulation and analysis of automotive collision safety and pedestrian protection as regard to the damage of automotive windshield.
