| 摘 要： | 本文结合环板在线性荷载作用下的塑性极限分析问题,给出一种简便的计算方法,即奇异函数法。文中用此法计算了具有外边界或内边界支承的环板的极限荷载,并画出几何参数对极限荷载的影响曲线。所得的结果具有良好的规律性而且是比较合理的。

| Abstract: | In this paper,a simple method on the plastic limit analysis of annular plates under linearly load has been given out. It is singular function method . With this method, the limit loads of annular plates at outside or inside boundary supporting have been calculated in this paper. The influence curve which shows the effect of the geometric parameter on limit load was traced. The computational results obtained in this paper are reasonable and with considerable regularity. |
