| Abstract: | In this paper, the yielding and hardening rules of gun-steel is first investigated through experiments. After being appropriately simplified, a two-linear mixed-hardening model is obtained. Then under the model, the shakedown of a thick-walled cylindrical tube subjected to internal pressure is analyzed. A method of defining the autofrettage of a thick-walled cylindrical tube is given from the viewpoint of shakedown. |
