摘　　要：在Mises屈服条件下,求解了外边简支内边自由环板和内外边均简支环板在均布荷载作用下的塑性极限荷载。Mises屈服条件是非线性的,文中采用加权残值法进行求解,得出了极限荷载下限解简洁的计算公式,并比较了Mises条件与最大极限弯矩条件的数值结果,结果是合理的。In this paper,on basis of Mises yield condition, the plastic limit load of annular plate with simply support under uniformly distributing load is evaluated. Because of the nonlinearity of the Mises yield condition, the weighted residual method is employed to gain the results. A simple formula for calculating the plastic limit load has been worked out. Compared with the results based on maximum moment condition,the numerical results in this paper are reasonable.
