| Abstract: | The result of the cyclic test on 25 gas cylinders of medium carbon manganese steel is presented in this paper. The tests show that the transition of the knucle and the cylindrical shell is the vulnerable spot in improper design or manufac- ture. In reference to the data of fatigue tests,a regressive curve of fatigue failure tests is obtained,and on the basis of this curve,with the safety factor 1.6 in stress and safety factor 8 in cyclic life,an optimum fatigue design curve for the cylinder base design is presented, which lies between the curves of ASME code and B. S. 5500 and is available for design use. |
