Or you can simply define a pretension load as you said. For a thermal load you're defining a displacement, d=alpha x T x L, given by the thermal expansion alpha. So if the stiffness, K, of the bolt is AE/L then F=Kd or F=AEalphaT.
WebIn a normal clamped joint K c is much larger than K b (R ≈ 5.0 for steel bolt and flanges), so that the bolt load does not increase much as the initial external load F e is applied. (Note that the bolt load does not increase significantly until F e exceeds F i.). In order to further clarify the effect of externally applied loads, a series of triangular diagrams (fig. 27, from … WebJul 18, 2024 · Bolt preload increased by approximately 33 percent at maximum temperature due to the higher thermal expansion of the aluminum plate.
