Modelling of Fracture Initiation and Post-Fracture Behaviour of Head Impact on Car Windshields

More than half of all road fatalities involve vulnerable road users, such as pedestrians and cyclists [1]. When involved in crashes with cars, the head is particularly susceptible to injuries, and especially if the road user hits the windshield of the car [2]. Impact tests are often performed to estimate the risk of head injury during such an event. A pedestrian head strike test normally involves a spherical headform, in which the likelihood of head injury is described by the head injury criterion (HIC) [3].
