摘  要:
On the basis of linear fracture mechanics in which the unwelding portion was treated as a crack and the maximum tangential stress theory of Erdogan, the author expounded a method to evaluate the fatigue fracture strength and brittle fracture strength for the unwelding portion between a cylinder and its bottom. This method is convenient for strength evaluation and optimum design of the cylinder. The strength evaluation flowchart described in the method provides the basis for analysis of the fatigue fracture strength and brittle fracture strength in the unwelding portion of load cylinder with random size. The ratiocinative method can be applied to other welded joints with similar structure.
