Abstract:
The plastic critical analysis of simply supported circular plates based on unified yield criterion under linear and uniformly distributed load was carried out, and two forms of loads were considered. The unified solutions which consisted of a series of analytical solutions based on different yield criterions were obtained and the relative curves between critical load and parameter value were also gained. The results of this paper can be used in the different materials of the same tension and compression strength by choosing different parameter values in the unified solutions. The solution of Mises criterion is a special case of the unified solutions. From the unified solutions, correct understanding the material strength and reasonable applying the yield criterion are very important to bring out latent potentialities in material strength.It has profitable economic benefits in the engineering applications.
