Abstract
A dynamic, nonlinear finite element method is applied to investigate the mechanical behavior of a human being head normally impacting on laminated glass plates. The human being head is modeled as a solid aluminum sphere covered with a viscoelastic skin. Both aluminum sphere and viscoelastic are deformable. Resultant accelerations in the head and maximum principal stresses in laminated glass plates are computed under various impact speeds and laminated glass configurations. The effect of impact speed and laminated glass configuration on the maximum resultant head acceleration before the failure of the laminated glass plate is studied.
