| 摘 要： | 圆板是工程中常见的一种结构形式。本文采用弹脆塑性木构模型，对弹塑性载荷作用下固支圆板的弯曲作了详细的分析研究，得出了对应材料残余强度系数不同取值范围的图板的承载能力解析表达式。文中对加载过程中屈服面的变化情况作了探讨。文未还给出了相应的简支圆板的弹脆塑性承载能力表达式。

| Abstract: | Circular plate is one kind of structure models which is popular in engineering. In this paper, the elasto-brittle-plastic constitutive model is used. The bending of circular plate under the action of elasto-plastic distributed lateral load is studied in detail. The analytical expressions of bearing capacity are obtained corresponding to different value ranges of the material's residual strength coefficients.The changes of the yelding surface occured in the loading process are discussed. At the end of this paper, the relevent expression of bearing capacity for simply supported cirular plate is also presented. |
