  • Patent number: 8453515
    Abstract: The invention provides fatigue testing of a material specimen while the specimen is disposed in a high pressure fluid environment. A specimen is placed between receivers in an end cap of a vessel and a piston that is moveable within the vessel. Pressurized fluid is provided to compression and tension chambers defined between the piston and the vessel. When the pressure in the compression chamber is greater than the pressure in the tension chamber, the specimen is subjected to a compression force. When the pressure in the tension chamber is greater than the pressure in the compression chamber, the specimen is subjected to a tension force. While the specimen is subjected to either force, it is also surrounded by the pressurized fluid in the tension chamber. In some examples, the specimen is surrounded by hydrogen.

  • Patent number: 8230748
    Abstract: A stress-strain testing apparatus imposes a stress-strain on a specimen while disposed in a controlled environment. Each end of the specimen is fastened to an end cap and a strain gage is attached to the specimen. An adjusting mechanism and a compression element are disposed between the end caps forming a frame for applying forces to the end caps and thereby stress-straining the specimen. The adjusting mechanism may be extended or retracted to increase or decrease the imposed stress-strain on the specimen, and the stress-strain is measured by the strain gage on the specimen while the apparatus is exposed to an environment such as high pressure hydrogen. Strain gages may be placed on the frame to measure stress-strains in the frame that may be caused by the environment.

  • Publication number: 20120118395
    Abstract: An apparatus for inducing cavitation at a surface of a specimen includes a cavitation chamber, a window extending through the wall of the chamber to an area outside the chamber, a test specimen positioned within the chamber, and a cavitation media inside the chamber and in contact with the surface of the specimen. A laser light source is disposed outside the chamber, and is operable to provide a laser beam through the window and into the cavitation media. The laser light source generates a shock wave in the cavitation media, the shock wave causing cavitation at the surface of the specimen.
