结构的反直观行为对其影响因素极为敏感
当任一参数有微小变化时
都可能影响到反直观行为的发生与否.本文针对材料行为对反直观行为的影响进行了研究.研究表明:对于厚度较薄的圆板
材料的屈服极限对反直观的发生范围影响不敏感;对于较厚的板
反直观行为发生的范围随材料的屈服极限的提高而大幅度减小
以至难以发生;材料的应变率效应是影响反直观行为的另一重要因素
在爆炸载荷作用下
不能忽略材料的应变率效应的影响.
Anomalous response is sensitive to various influencing factors
when a parameter has small changes
it is likely to affect whether or not the occurrence of anomalous response.Effects of material properties on anomalous response under blast loading was studied.The results show that for the thin circular plate
the occurrence of the range of anomalous response is insensitive with material yield limit and for the thicker circular plate
the range of anomalous response with the material yield limit increasing drastically reduces
even difficult to occur.Strain-rate effect is another important factor for anomalous response and strain-rate effect can not be ignored under blast loading.
