DYNAMIC ANALYSIS OF NORMAL IMPACT OF OCCUPANT HEAD ON LAMINATED GLASS

The paper discusses a study that applied a dynamic, nonlinear finite element method to investigate the mechanical behavior of a human head normally impacting on laminated glass plate. The head used is modeled as a solid aluminum sphere covered with a viscoelastic skin; both the aluminum sphere and the viscoelastic are deformable. The study computes the resultant accelerations in the head and maximum principal stresses in laminated glass plates under various impact speeds and laminated glass configurations. Also examined is the effect of impact speed and laminated glass configuration on the maximum resultant head acceleration before the failure of the laminated glass plate.
