WebThe six types of stress in an aircraft are described as tension, compression, shear, bearing, bending, and torsion (or twisting). The first four are commonly called basic stresses; the last two, combination stresses. Stresses usually act in combinations rather than singly. [Figure 1] Figure 1. Stresses in aircraft structures. WebOct 15, 2016 · FLUCTUATING STRESSES The failure points from fatigue tests made with different steels and combinations of mean and variable stresses are plotted in figure as functions of stress amplitude(σa) and mean stress (σm). The most significant observation is that, in general, the failure point is little related to the mean stress when it is ...

Cyclic stress is the repetitive occurrence and redistribution of forces acting on a material. Periodic or regular cyclic stress conditions lead to increased wear and tear of the material, thus increasing the rate of material degradation and failure.
