<P>PROBLEM TO BE SOLVED: To provide a sample for tensile test, which is suitably used in a tensile test of a tubular material. <P>SOLUTION: In a sample for tensile test of a tubular material 1, which is used in a tensile test, a plurality of slits 2 extending in an axial direction are formed around the tubular material 1 to form test piece parts 3 between the slits 2. Therefore, the sample for tensile test can be pulled in a tubular state as it is without the reduction in diameter when the tensile test is performed, so that accurate measurement with uniaxial tension is possible while preventing the occurrence of a bending moment, the occurrence of warpage in a longitudinal direction, and the like due to the reduction in diameter of each test piece part 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
