title: The time-dependent mechanical properties of skin.
abstract: The mechanical properties of the skin were investigated by applying a torsional deformation to a circumscribed area. Results of the tests indicate that the skin is nonlinear and time dependent. The dynamic response shows that the phase angle is insensitive to frequency below 1 Hz; the peak torque amplitude increases slowly above 0.004 Hz. A self-consistent description is presented utilizing continuous relaxation spectra. The technique describes the stress relaxation data and predicts the form of the dynamic response.
