“…A number of authors have proposed that the skull is best thought of as a thin spherical shell that is incompressible in the thickness direction but supports bending and stretching parallel to the surface. 6 This model has been employed frequently in the head injury literature, 6,9,10 as well as by a few researchers studying bone conducted sound. 6,11,12 It has not, however, been universally accepted largely due to the lack of experimental measurements that support it.…”

The results of a study of the three-dimensional vibration of two dry human skulls in response to harmonic excitation are presented. The vibratory response exhibits three distinct types of motion across the range of audible frequencies. At low frequencies below 1000 Hz, whole-head quasi-rigid motion is seen. At the middle frequencies between 1000 and 6000 Hz, the motion exhibits a series of increasingly complex modal patterns. Above 6000 Hz, the response is wavelike and clear wavefronts can be distinguished in the vibration data. In this regime the relationship between wavelength and frequency is calculated and compared to a number of theories of skull vibration that have been proposed.

“…The previous observations led Viano and Lau [77,78] to propose a viscous injury mechanism for soft biological tissues. The viscous response (VC) is defmed as the product of velocity of deformation (V) and compression (C), which is a time-varying function in an impact.…”

“…Kopecky and Ripperger [76] showed experimentally and computationally that cavitation can occur as a result of a 150g acceleration. Analysis of the CSF response has, in the past, been limited to fluid-filled shells with the brain taken as a nearly incompressible homogeneous fluid and the skull as a thin spherical or ellipsoidal shell [76][77][78][79][80].…”
