| 摘 要： | 本文采用俞茂宏统一屈服准则对固支圆板、矩形板进行了塑性极限荷载分析,得出了相应的统一解形式。选择不同的参数b,可以得出不同工程材料的塑性极限荷载,具有较好的普遍性和适用性。文献中已有的解均为本文的特例。

| Abstract: | In this paper, adopting the Yu's (Twin Shear) Unified Yield Criterion, we perform the limit load analysis of two problems: one is fixed circular plate and the other is rectangular plate under uniform out-of-plane loading. Unified solutions are obtained and some available solutions based on Tresca, Mises and Twin Shear are also the special cases of the unified solutions. The unified solutions can be used for different materials. |

| Keywords: | Yu's unified yield criterion fixed circular plate rectangular plate plastic limit load. |
