Abstract
1,086,337. Testing tensile stress. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 25, 1966 [Sept. 2, 1965], No. 38227/66. Heading G1S. A high-speed tensile testing machine comprises a stationary cylinder block 1 which is fitted internally with a movable piston 4, a piston rod 5 coupled to the extremity of a test piece 7, a rigid head 9 positionally adjustable relatively to said stationary cylinder and coupled to the other extremity of said test piece, means whereby a compressed gas at variable pressure is admitted into a space 24 in said stationary cylinder block 1, a shearing member 15 which provides a temporary coupling between said movable piston and said stationary cylinder and which is adapted to fail by fast shear fracture initiated by explosive means. The coupling 15 is in the form of two detonation tubes which are positioned in a bracket 14 at the start of the operation. A compressed gas or compressed air-pressure is admitted into a tubular chamber 38 which forms part of the hydraulic brake and the pressure within a bottle 26 is regulated to a predetermined value. When this pressure has been reached valves 32, 30 are opened and a pressure exerted on the upper face of piston 4. At this moment the detonation tubes 15 are fixed causing rupture at the weakened position which allows the pressurized gas in space 24 to expand and force piston 4 downwards. Thus a tensile stress is exerted on the test piece with sufficient acceleration to obtain the desired speed. At the end of travel the piston 4 contacts a piston 35 of the hydraulic brake which drives oil 39 back into the tubular chamber 38 displacing the compressed gas 40. A compressor is connected to bottle 26 through non-return valve 29.
