摘要： PROBLEM TO BE SOLVED: To provide a test piece and a fatigue life evaluation method, capable of evaluating a fatigue life of a pipe by surely causing a crack in a welded portion of an inner surface of the pipe.SOLUTION: A test piece 1 for fatigue life evaluation having a welded portion 3 between two metal piping portions 2 having the same shape is cut out from a pipe. A surface corresponding to the inside of the pipe, of the test piece 1 is formed in the same shape as the inside of the pipe. A surface corresponding to the outside of the pipe, of the test piece 1 has a continuous curve in connecting portions 6 between the welded portion 3 and the metal piping portions 2. A ratio of a distance from a central axis C of the test piece 1 to respective apexes corresponding to the inside and the outside of the welded portion 3 is set to 1 or more. The test piece 1 is arranged so as to be deviated from a load central axis so that the load central axis of a fatigue life evaluation device is located in a direction of the inside of the pipe from the central axis C. A tensile load and a compression load are repeatedly applied to the test piece 1 arranged in this way, and the number of repeated times until a fatigue crack occurs in the welded portion 3 or the connecting portions 6 is acquired.
摘要翻译：要解决的问题：提供一种试验片和疲劳寿命评估方法，其能够通过确保在管的内表面的焊接部分中的裂纹来评估管的疲劳寿命。解决方案：将具有相同形状的两个金属管道部分2之间的焊接部分3的用于疲劳寿命评估的试件1从管中切出。与试管1的内侧相对应的面形成为与管内相同的形状。与试验片1的管的外侧相对应的表面在焊接部3与金属配管部2之间的连接部6具有连续的曲线。与试验片1的中心轴C的距离对应于焊接部3的内侧和外侧的各顶点被设定为1以上。试验片1被布置成偏离负载中心轴线，使得疲劳寿命评估装置的负载中心轴线位于从中心轴线C的管道内侧的方向上。拉伸载荷和压缩载荷被重复施加到以这种方式布置的试验片1，并且获得在焊接部3或连接部6中发生疲劳裂纹的重复次数。版权所有（C）2013，JPO＆INPIT
