| Abstract: | Expressions denoted with internal forces arc often used in the limit analysis in plastic stage. In this paper, the author proposes to use a moment expression of Mohr-Coulomb in the case of limit analysis of circular plates in plastic stage. This proposal is useful in the analysis of load carrying capacity of circular plates composed of rock or concrete. |
