£Ábstract: Based on the model theory of elastoplastic theory and the plastic deformation theory, an analytical method is shown in this paper. The method is achieved by the step: first, the elastic solution is obtained from experiment or computation, and then, based on generalized stress-strain curve of material and Iliushin theory of plasticity, this elastic solution is transformed into elastoplastic stress solution in the related structures. It is shown by examination that the method is reasonable.
Keywords: elastic solution, elastoplastic stress analysis.
