Conclusion: The increase in mechanical properties may be a response to repeated stress and may function as a mechanism to resist tendon damage due to mechanical fatigue.
结论：跟腱力学性质的变化是对重复应力刺激的一种反应，是肌腱对抗力学疲劳的机制。
When the load is the stress cycle, the mechanical properties of materials caused by the deterioration process is known as fatigue damage.
当荷载是循环往复应力时，引起的材料力学性能劣化过程称为疲劳损伤。
The results showed that fatigue damage could lead up to the degeneration of the mechanical properties to a certain extent.
结果表明，疲劳损伤会引起材料力学性能产生一定程度的退化，这一退化现象与试样表面短裂纹的演化过程密切相关。
The concrete constitutive properties coupling damage can be used for finite element analysis of concrete under fatigue load.
由此建立耦合损伤变量的混凝土本构关系模型，可用于疲劳荷载作用下混凝土的有限元分析。
