Summary The present study is concerned with determining the dynamic characteristics of the human head-neck system which is described as a fluid-filled spherical cavity supported by a viscoelastic neck reacting in three dimensions. The material of the skull is assumed to be a homogeneous, isotropic, elastic material, and that of the brain-cerebrospinal fluid as an inviscid irrotational fluid. The neck is approximated by a three-element viscoelastic model, the constants of which are computed by using experimental data. The obtained results show that the viscoelastic properties of the neck affect only the first two eigenfrequencies and the corresponding damping coefficients, while the remaining spectrum remains unchanged.
