可恢复的应变能量是一种在缠绕过程中被储存的弹性能。
The recovered energy is the elastic energy that is stored during reeling.
当荷载被移走时，应变的弹性部分恢复，但塑性应变部分(滑移和徐变)却会永久呆留。
When the load is removed, the elastic portion of the strain is recovered, but the plastic part (slip and creep) remains as permanent set.
轴向回跳的原因是轴向弹性应变的恢复快于轴向塑性应变的增加。
The reason for axial snap-back is that the recovery of axial elastic strain is faster than the increase of axial plastic strain.
