axial strain change

The amplitude of the loss peak decreases linearly with axial strain, whereas, it is hardly affected by temperature change.

谐振波长随温度和轴向应变线性变化，透射峰幅值随轴向应变线性减小但对温度不敏感。

Simulation results show strain distribution of workpiece and how outer diameter, thickness, axial elongation of some typical nodes change with time.

分析了毛坯的应变场分布，典型节点外径、壁厚、轴向伸长量随时间的变化曲线，对整个成形工艺及变形机制有较好的动态认识。

It is shown that the observed volume change in tests can be predicted accurately with the proposed relationship between lateral and axial strain.

所建立的侧向应变与轴向应变间的关系能够对三轴试验中的体积变化进行符合试验情况的描述。
