Abstract : The report contains the results of a study to develop a theoretical approach whereby uniaxial fatigue data can be used to predict the permissible number of cycles of a thick-walled cylinder. Experimental data from the literature were examined on open end and closed end cylinders in an autofrettaged and non-autofrettaged condition with wall ratios from 1.2 to 2.0. Distortion energy was used to reduce the triaxial stress state to an equivalent uniaxial stress. A new method was then developed whereby the number of cycles could be predicted as a function of the mean and alternating pressure. (Author)
