The mechanical behaviour of the flexor tendon of the human hand is here investigated from the point of view of its nonlinear viscoelasticity. The samples are subjected to several single and multiple step loading histories. A quasilinear viscoelastic constitutive relationship between strain and stress history is assumed. Its characteristic material functions are determined with the aid of simple creep results, and model predictions are compared with the experimental results of complex loading histories. The validity of the quasilinear approach to tendon behaviour is discussed in connection with the deformation mechanism suggested by it.
本文从人手指屈肌腱的非线性粘弹性角度研究其力学行为。对样本施加了几种单步和多步加载历程。假定应变与应力历程之间存在准线性粘弹性本构关系。借助简单的蠕变结果确定其特征材料函数，并将模型预测结果与复杂加载历程的实验结果进行比较。结合准线性方法所提出的变形机制，讨论了该方法对于肌腱行为的有效性。
