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 WebThe steady and fluctuating design stresses as produced by the propeller absorbing power in a variable wake field represent only one aspect of the total blade stress distribution. Residual stresses, which are introduced during manufacture or during repair, represent the complementary considerations.
