| Abstract: | A new cross specimen under biaxial loading was designed for the reguire of studing fatigue behaviour at the junction of vessel and nozzle. There is a good agreement between the computed results by FEM and the experimential data. The results showed that the characteristic of the strain distribution in the cross specimen is same as that at the junction of vessel and nozzle; peak strain, great strain gradient,elastic field all around. |

| Keywords: | nozzle of the vessels stress and strain cross specimen |
