摘要

Based on a criminal case we report on laboratory tests and the ensuing biomechanical assessment regarding the injury potential of stones deliberately thrown at oncoming vehicles that can break through the windshield and hit the occupants. Through life-size experiments, the values of residual kinetic energies of plum-sized stones (mass up to approximately 100 g) after breaking through the windshield were determined. We found out that under the circumstances of the study, in unfavorable situations the residual energy of the stone within the vehicle interior could reach levels sufficient to cause skull fractures and corresponding intracranial injuries.
