The book deals with the stochastic strength of glass and the application to the automotive windscreen. A finite element model is derived. This is then validated using known phenomena in connection with the fracture behaviour of glass. After the strength of a windscreen has been intensively investigated, experiments with wind windscreen, experiments with windscreens are simulated by means of the model. Finally, the probability of a pedestrian suffering a head injury on impact with a windscreen is predicted. of a pedestrian hitting a windscreen is predicted, taking into account the stochastic breakage behaviour of glass. Up to now, this has not been taken into account in EuroNCAP crash tests, for example.
