Skull biomechanics: The energy absorbability of the human skull frontal bone during fracture under quasi-static loading

Four human skulls were studied in order to determine the energy absorbed corresponding to a fracture due to quasi-static loading on the frontal bone. Using a dedicated experimental set up, the force-deformation characteristics of the specimens were recorded, calculating energy absorption. Mean value...

Summary:Four human skulls were studied in order to determine the energy absorbed corresponding to a fracture due to quasi-static loading on the frontal bone. Using a dedicated experimental set up, the force-deformation characteristics of the specimens were recorded, calculating energy absorption. Mean values of 1975 +/- 703 N, 4.17 +/- 0.81 mm and 3.95 +/- 1.18 J were found for the peak force, maximum deformation and absorbed energy to fracture, respectively. Linear fractures were always seen in the frontal bone, with a similar pattern in three of the four skulls. These results can be used to develop bench-mark skull models to validate analytic models.
