Flame straightening stress calculation

WebBecause the mechanical shaft straightening method does not require the use of heat, it can be used on a wider range of shaft materials than the spot-heating process. Disadvantages: The mechanical shaft straightening … Webstress is applied. The function of the creep test is to determine the creep rate and amount of deformation as a function of applied stress, time, and temperature. While the method of measuring creep is simple enough in principle, satisfactory results require precise control of furnace temperature, specimen alignment, and applied stress.
