| Abstract: | Thispaper makesan autofrettage analysisof thick walled cylinder of material with different yield strength in tension and compression based on unified strength theory.The stressdistribution and residual stressdistribution are obtained by the analysis,from which a set of solutionscan be obtained based on different strength theoriesfrom the Mohr strength theory to the twin shear strength theory.The optimum elastic-plastic radiusand optimum autofrettage pressure are obtained by the analysis.The resultsin the reference are only the special solution.By using the unified strength theory,the more proper solution about different materialscan be obtained. |
