    Abstract:

    ABAQUS is used to simulate 6 different hollow specimens with different wall thickness and height, six stress components and three principal stress in a cylindrical coordinate system were summed up, and the end effect of stress distribution of properties were analyzed. Results showed that, the intermediate principal stress σ2 and radial stress σr within each of the height of about 10% at the ends, circumferential stress τzθ, axial stressσ1 and σ3 of about 20% at each end are under the influence of end effect. There are errors between real stresses of the sample end and middle, the decrease extent of σr and σθ are about 20%, 30%, respectively, and the errors of σz and τzθ are positively correlated with the thickness of the specimen. In order to reduce the effect of end-effects, the ratio of height to width is recommended to be 2.5, the ratio of inner to outer diameter is 0.8.
