With a device for dynamical processes tension tests were performed on bundles of collagen fibres of human and bovin origin. Part of the studies were performed under statical condition with an universal materials testing machine, equipped with a closed loop feed back control system. If the force is to be kept constant subsequently to a strain process on a collagen fiber bundle (isotonic condition), the fiber length must increase (creep phenomenon, retardation). The force decreases under constant length after a preceding strain process (relaxation). In analogy to the statical relaxation, statical isorheological line, and statical force recovery curve the dynamical (cyclic) relaxation, dynamical (cyclic) isorheological curve, and dynamical (cyclic) force recovery curve are described. The mechanical-rheological properties collagen fiber bundles are discussed in relation to functional anatomy.
使用一种用于动态过程的装置，对源自人类和牛的胶原纤维束进行了拉伸试验。部分研究是在静态条件下，使用配备闭环反馈控制系统的万能材料试验机进行的。如果在胶原纤维束上进行应变过程后要保持力恒定（等张条件），纤维长度必须增加（蠕变现象、延迟）。在先前的应变过程后，在恒定长度下力会减小（松弛）。类似于静态松弛、静态等流变线和静态力恢复曲线，描述了动态（循环）松弛、动态（循环）等流变曲线和动态（循环）力恢复曲线。结合功能解剖学讨论了胶原纤维束的力学流变特性。
