DEVICE FOR TENSILE TEST AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A tension test device and a manufacturing method thereof are provided to apply pure circumferential tensile strain to a cylindrical specimen by changing the axial compressive load of a cylindrical sample to the radial direction of a sample. CONSTITUTION: A tension test device is composed of a supporting unit(110) and a moving unit(120a). The supporting unit supports the axial compression load of a cylindrical sample. The supporting unit is moved to the compressed direction by the compression load. The moving unit is supported to the inner circumference of the sample. The moving unit is moved according to moving of the supporting unit. The moving unit circumferentially applies tensile strain to the sample.
