Abstract : There is a long-standing interest in developing a capability to predict the distribution of retained stresses in thick-walled tubes after the removal of an internal pressure-post autofrettage. In this report, four different methods of calculating such stresses are presented and compared. The methods presented are based on the following assumed yield criteria and deformation conditions: (1). Tresca's yield criterion (2). Tresca's yield criterion 2/3 (3). Mises' yield criterion in plane-stress (4). Mises' yield criterion in plane-strain Autofrettage, Mck-Walled Tubes, Stress Distribution, Retained Stresses, Tresca's Yield Criterion. Mises' Yield Criterion. Plane-Sum. Plane-Strain.
