肌腱及其末端结构的断裂特性实验观察

A EXPERIMENTAL INVESTIGATION ON THE FAILURE PROPERTIES OF TENDON AND IT'S INSERTION

对兔髌骨－髌腱－胫骨结节和跟腱－跟骨试件的组织结构观察，应力－应变关系本构方程和力学特性的测定，发现肌腱的力学强度明显高于牵拉屈折型和滑车型腱末端，而与牵拉型末端无明显差异。

The purpose of this work is to investigate the mechanical properties of patellar tendon, Achilles tendon and it's insertions. In the experiment three types of insertion was found under microscopy. They are trochlea, pulling, and pulling--inflectlve insertion. The stress-strain coefficients had great difference between tendons and insertions. The mechanical strengths of tendons were more higher than the trochlea and pulling' inflective insertion. The difference of strengths between tendon and pulling insertion has not significant.
