    New Nukes with Dem Administration?

    What do you guys feel is the future of New Nukes or expansions of existing units with a Demorat Administration? I do not want a political discussion, just what are your thoughts for the industry with these new people coming in? I sell testing equipment to your industry and I am a bit worried...

    750C tensile test furnace for optical strain measurement of Inconel

    14 Years, MTS has a very nice induction system, small cols that wrap around the sample and not touch it. Usually used for higher heat ranges but can be used for this application. Good luck with the vision system and the heat, the people I know that used that threw it away and started over...

    Elongation at Break

    Airrider 04, I have problems with the results you have: Mat'l 1 Yield = 70300psi Ultimate = 84800psi Elongation = 14% Mat'l 2 Yield = 76500psi Ultimate = 86000psi Elongation = 26% You have a 14KSI difference between Yield and tensile and 14%...

    HDT test - deflection v. time curves

    Hello Entanglement, HDT and Vicat machines now come with the data acquisition that you are looking for, contact Tinius Olsen Testing Machine Co. (www.tiniusolsen.com) for more information and a quotation. All the tests that I have seen, (less than 50), have shown a non-linear curve. More and...

    Tensile testing of Hard thin steel....

    NickE Try this, it is similar to the diamond slurry but not as messy. Try Crocus cloth, it is used in polishing and is normally about 2 inches wide. The carbide on the cloth will help get a better grip on the material. YOu need more surface area to hold onto the sample. You can also...

    Radio Station Power Output to surroundings

    Hello, Not sure if this is the right place to post, if not please point me to right area. A radio station is planning new towers in my neighborhood, around 25K Watts, both Am and FM stations. 2 Towers about 100 ft. apart and 100 to 150 ft. high. What is the equation to tell me how much power a...

    Steel Reinforcement Test To BS4449

    albert1, You must also check the location of the break after the tensile test. If it breaks near the grip, it will more than lokely fail the elongation. If it breaks in the middle area of the sample look for discontinuities in the steel, a lamintation, roll mark and other items, any...

    Tensile machine performance

    To PrentP: The modulus calculation (Delta Stress / Delta Strain) is dependent upon BOTH load and Elongation. If you are using a clip-on extensometer you have to make sure BOTH the LOAD and Strain are calibrated. If you are using the crosshead position as the elongation device you have to...

    Torsion test

    Brite, There is no good way to do torsion using a UTM. Baldwin used to have a tool but it proved cumbersome and unreliable. Depending upon the size of the sample there are 3 companies that have torsion machines from 10,000 in-lb. to 400,000 in-lb. They are Tinius Olsen TMC Inc...

    Do conversions for ASTM to JIS tensile test results exist?

    Nick, Conversions to what, from ASTM to JIS? The difference between the 2 is the gage width of the sample, 0.500 for the ASTM to 0.94 or so for the JIS. The elongation will be higher on the JIS, more material to stretch, the n-value and r will be relatively unchanged, but may be slightly...
