%X Force and deformation of the specimen during ring hoop tension test were analyzed. Distribution of radial normal force and hoop tension force were discussed and equations derived. FEM analysis and experiments were carried out to verify the theoretical analysis. Results show that the FEM and experimental results agreed well with the distribution of hoop tension fore. The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.
