1) the cylinder shell partly plastic unsteadiness under tenson
圆柱壳局部拉伸塑性失稳
3) local plastic instability
局部塑性失稳
1.
The thermal viscoplastic constitutive equation was established by the impact compression and the impact shearing tests by the split Hopkinson pressure bar(SHPB),the process of local plastic instability at higher strain rates was analyzed,the criterion of plastic instability was obtained,and the nature of the high strain rate sensitivity for local plastic instability was revealed.
通过ZA8,ZA27和ZA35合金在Hopkinson测试系统上的冲击压缩试验和冲击剪切试验,建立了材料的热粘塑性本构方程,分析了高应变率条件下的局部塑性失稳过程,得到了塑性失稳准则,揭示了局部塑性失稳的高应变率敏感性本质。
4) elastic-plastic stability theory of thin shell structure
圆柱薄壳结构弹塑性稳定性
6) Tensile Failure
拉伸失稳
1.
On the Tensile Failure and Material Failure in the Tensile Test of Metal Material;
论金属材料拉伸试验中的拉伸失稳与材料失稳
2.
More attentions to the tensile failure in tension test are paid;but the material failure is overlooked.
在材料力学的常规拉伸试验中,往往仅关心拉伸失稳而忽视了材料是否失稳。
补充资料：裂纹失稳扩展
分子式：
CAS号：
性质：材料内部裂纹尖端的应力场强度因子达到或超过材料的断裂韧性之后发生的裂纹快速扩展。裂纹失稳扩展将导致材料迅速断裂。
