Notes:
Used pipes in various mechanisms and structures are produced from raw material byextruding and drawing. The properties such as yield strength, tensile strength, and elongation of apipe produced by these methods are different from the properties of their raw material. Butdesigners use the properties of the raw material because the actual properties of the pipes aredifficult to obtain from testing. Also, the pipe is used after it has been bent in a complex manner andcut to fit it to mechanisms and structures. The bending process, especially, induces deformation ofthe pipe’s section and residual stress, which are involved in the plastic deformation of the bendedpipes. This residual stress affects the pipe’s properties, including its fatigue life. Therefore, it is veryimportant to understand the residual stress of a material. But, the distribution of residual stress of aU-shaped pipe, which is examined in this study, is very complicated and cannot be measuredexactly
