| Abstract: | In this paper,the crucial calculating formulas for stresses, displacements, excess, degrees of autofrettage, permanent bare enlargement and push force etc. of mechanical autofretted thick-walled cylinders with bilinear materials have been obtained by an ealsto-plastic analysis with due considerations of reasonable assumptions and the actual strain hardening and Bauschinger effect. And the results of the theoretical calculations of this paper are in accord with the corresponding experimental values. |

| Keywords: | Mechanical autofrettage Thick walled cylinders Residual stresses Mixed hardening excess. |
