| Abstract: | This paper makes the Autofrettage analysis of thick wall spherical shell of linear strength material based on unified strength theory. The stress distribution, residual stress distribution, the optimum elasto-plastic radius and optimum autofrettage pressure have been obtained by the analysis. The results in the reference are only the special solution. By using the unified strength theory, the more proper solution about different materials can be derived. |
