Abstract

PURPOSE:To eliminate the need for any complicated operation in alignment between a pressure vessel and a load applying apparatus by providing a load applying means integrally with one component of the pressure vessel, and providing an inside bearing means inside said pressure vessel. CONSTITUTION:The pressure vessel 10 comprises two components, a vessel main body 12 and a cap body 14. A load applying cylinder 20 is fitted on a seal cap part 14b through a load supporter 22 so as to be integrally connected with the cap body 14. The upper part of a test piece 26 in the pressure vessel is connected through a chuck 28a to one end of a load rod 18, while the lower part of the test piece 26 is secured to a cap plate 14, through a chuck 28b, a nut 28c, an inside bearing base 30a and supports 30b screwed into the cap plate 14, in order to make the test piece 26 bear a load. By applying an oil pressure P2 or P3 to the load applying cylinder 20, a tensile or compressive stress is applied to the test piece. If the oil pressures P2 and P3 are alternately applied thereto, a fatigue test can be carried out. Whereby, it is possible both to miniaturize the tester and to apply an acruate stress.
