Material strength testing equipment

Abstract

Abstract PURPOSE:To make it possible to perform a strength test in such a state testing stress is set arbitrarily, by a small apparatus having such a mechanism that the piston in a pressure chamber having a test piece fixed thereto is formed into a two-step diameter structure having different diameters and providing three pressure chambers so as to correspond to the leading end part, intermediate part and rear end part of the piston. CONSTITUTION:The upper end of a test piece 1 is fixed to a casing 2a and the lower end thereof is fixed to a piston part 3a. A piston 3 is formed onto a two- step diameter structure having different diameters and seal mechanisms 9, 10 for performing water seal are provided between the piston 3 and the casing 2a. A pressure chamber A sets the pressure environment of the test piece 1 and high temp. and high pressure water is introduced into said chamber A. A pressure chamber B is filled with pressure water for loading the test piece 1 and, by controlling differential pressure between the pressures of the pressure chamber B and a pressure chamber C, arbitrary load can be loaded.
