- Abstract
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.
