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.
通过对外围区域施加扭转变形来研究皮肤的力学性能。测试结果表明，皮肤是非线性且与时间相关的。动态响应表明，在低于1Hz的频率下，相位角对频率不敏感；在高于0.004Hz时，峰值扭矩幅度缓慢增加。利用连续松弛谱给出了一种自洽描述。该技术描述了应力松弛数据并预测了动态响应的形式。
