圆板(在Mises准则下)全屈服后载荷与挠度的关系

The Load-Deflection Relationship of Circular Plates in the Perfectly Plastic Range(on Mises Criterion)

利用Ｏａｎｔ近似分析理论研究了理想刚塑性材料圆板在中心冲压载荷作用下，进入全塑性状态后的承载能力，得出了圆板结构在塑性范围的Ｐ－δ曲线。

An approximate analysis of load carrying capacity of circular plate structures in perfectly plastic state is presented in this paper.The material of the plates is ideal rigid plastics.In this way,the load-deflection relationship of p-δ of circular plates is formed according to Mises criterion.A comparison between theoretical analysis and test results is favourable.
