While tendons have enormous tensile strength, they have very little tolerance to stretching.
肌腱具有很大的抗张强度，它能承受的伸展度也非常小。

If mating anchorages and stretching devices are selected carefully, and tensile stress and elongation are controlled, the unbonded prestressing will certainly meet its quality requirements.
本工程注意选择配套锚具及张拉设备，控制张拉应力及伸长率，使无粘结预应力达到质量要求。

In order to obtain the mechanical properties of rubber's hyperelastic parameters, the general means is based on the traditional uniaxial tensile, biaxial stretching and other methods.
