Flame straightening stress calculation
WebLinde plc 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.

Many condition. engineers are reluctant to allow heat straightening because 3. Webproportional-limit stress, as a result of the aforementioned aging or application of mild heat. Two facts emerge from this brief discussion of cold bending: 1. The same allowable stresses (or load factors) can be applied to cold-cam-bered beams as to uncambered beams, provided that they are allowed to “age” for a few hours. 2.
