1) necking criterion
颈缩判据
2) shrinkage porosity criterion
缩松判据
1.
Study on shrinkage porosity criterion under pressure conditions;
压力条件下缩松判据的研究
3) a rule for shrinkage
无缩孔判据
4) recompression criterion
再压缩判据
1.
The method of characteristics was introduced to calculate the flow field after the primary nozzle exit,whilst Korst s recompression criterion was adopted to determine the corresponding cell pressure,and one-dimensional control volume method was employed to analyze the downstream flow field.
该方法采用特征线方法分析一次流喷嘴出口流场,结合Korst再压缩判据确定引射器盲腔压力,采用一维控制体方法计算第二喉道引射器的下游流场。
5) shrinkage criterion
缩孔缩松判据
1.
In order to solve this problem, this work improves the shrinkage criterion—Time Gradient Method(Xue Criterion).
大多数缩孔缩松判据都忽略了液态金属静压力的影响,因此对液态金属静压力较大的铸件的缩孔缩松预测不够准确。
6) necking
[英]['nekiŋ] [美]['nɛkɪŋ]
颈缩
1.
Analysis of necking under condition of uniaxial tension of low-carbon steel specimen based on gradient-dependent plasticity;
基于梯度塑性理论的单向拉伸低碳钢试样颈缩分析
2.
This criterion is based on the critical thickness gradient C which occurs perpendicular to the necking when the failure develops.
介绍了一种预测板料发生颈缩的新准则——厚度梯度准则,该准则基于当板料发生颈缩时沿垂直于颈缩方向的厚度梯度分布存在着极值C;在板料成形过程中,当其厚度梯度值小于临界厚度梯度值C时,认为板料发生颈缩。
3.
This criterion was based on the critical thickness gradient RC which existed in the direction perpendicular to the necking when the failure developed.
介绍一种预测薄板成形极限的新准则——厚度梯度准则,该准则基于薄板颈缩时沿垂直于颈缩方向的厚度梯度分布存在极值RC。
