弹性后效

实际工程中，土体的变形很复杂，动力荷载比静载更容易使土体发生蠕变、应力松弛、弹性后效等流变特性。

Among the actual project , deformation , soil of body very complicated , it is apt to make soil body take place creep , stress lax , elastic aftereffect , etc. rheology characteristic than quiet year for power to load .

试验证明，其压制压力和弹性后效较YT5粉末都有显著的提高。

The test show that the pressing-pressure and elastic after-effect of the YF06 are remarkably higher than the YT5 .

高含量添加Ta（＞10%）后，粉体成形性得到改善，即弹性后效降低，压坯密度提高。

Compressibility of powders is improved when more Ta is added ( > 10 % ), namely green 's spring back is declined and pressed density increased .

为深入了解含Fe-Mo-B预合金粉的铁基合金的温压行为，研究了不同成形温度、不同Fe-Mo-B预合金粉含量对压坯密度、弹性后效以及样品显微组织和力学性能的影响。

For understanding the shaping behavior of iron-based alloy consisting Fe-Mo-B pre-alloyed powder during warm compaction ( WC ), the influence of the compacting temperature and the amount of Fe-Mo-B pre-alloyed powder on the green density , residual elasticity and microstructure was studied .

通过对卸载方程的分析显示，压制中粉末温度升高使得压坯的变形恢复更小，体现了高速压制弹性后效低、脱模压力小的特点。

The equation shows that the increasing of temperature makes the elastic aftereffect lower . The characteristics of high velocity compaction can be observed that elastic aftereffect is low and ejection pressure is small .

根据我国核电发展的需要，对中孔环形燃料芯块的制造进行了研究：通过试验确定了生坯成形后的弹性后效，烧结后的收缩率；

According to the requirement of nuclear power developing in our country , we studied the manufacturing of fuel pellets with central hole : we determined the elastic after-effect of green pellets and the shrinkage after sintered through experiments ;

重点探讨了脱模后的残余应力及保压脱模问题，提出弹性后效应力是制品脱模后所受的主要残余应力，论述了保压脱模的作用。

This article focuses on the residual stress of Stripping and post-packing Stripping . Propose that the main residual stresses of products after Stripping is mainly received after-effects of elastic after , and discuss the role of holding pressure stripping .
