unloading curve

Each section curve is regarded as a spline curve, then make use of springback simulation result after unloading of the spline and some modified value such as friction, clearance, press margin power and round radius of punch to predict each section springback.

每个截面曲线看成样条曲线，由样条卸载后的回弹仿真，加上利用神经网络法预测成形中摩擦、间隙、压边力、凸模圆角半径等影响的修正量来预测每个截面的回弹。

The unloading-rebound curve of the soft soil can be roughly divided into two stages, initial rebound stage and snapback stage.

珠海滨海相软土卸载回弹曲线大致可以分为两个阶段，回弹初始阶段以及第二阶段的快速回弹阶段。

The results indicate that the stress-stain curve of the honeycomb cardboard will first move up to the point of the unloading value with the secondary loading.

结果表明，二次加载时，蜂窝纸板的应力&应变曲线将首先上升到预压时的卸载点。

If the structure is elastic the force-displacement curve follows the same path on loading and unloading.

如果该结构为弹性者,那么在加载和卸载时力位移曲线遵循相同的迹线.
