WebObtain von Mises stresses for both midrange and alternating components. Apply appropriate K f to each type of stress. For load factor, use k c = 1. The torsional load factor (k c = 0.59) is inherently included in the von Mises equations. If needed, axial load factor can be divided into the axial stress. Shigley’s Mechanical Engineering Design WebMar 8, 2024 · So, study of fluctuating stresses came needed to make design safer. Since, c yclic stress variations were irregular and non-analytic, various models came in suggestion for the study. AT LAST, Sine curve came to be taken as the easiest and popular model. This model was based on Stress -Time relationship.
