WebbThe theoretical stress-concentration factors for the fillet are 3.0 and 1.8 for the axial and torsional loading, respectively. Assume the load variation P is synchronous with shaft rotation. With f = 0.3, find the maximum allowable load P such that the shaft will survive a minimum of 10^ {6} 106 cycles with a factor of safety of 3. WebbThe theoretical stress concentration factor is a function of component geometry and loading. Analytical expressions for stress co ncentration factors may be found in Mott (2008), and Pilkey (1997). Stress concentration factor K t for plate with hole under tension is shown as a function of the diameter to width ratio, d/b in Figure 1.

WebbThe values of the Finite Element (FE) calculated Theoretical Stress Concentration Factors (TSCF’s) are computed, for the case of short circular cylinders with circular holes subjected to axial tension, and presented in a fashion similar to existing published results. WebbA theoretical stress-concentration factor Kts of 1.6 is induced by the 1/8-in fillet. The length of shaft A from the fixed support to the connection at shaft B is 2 ft. The load F cycles from 100 to 500 lbf. (a) For shaft A, find the factor of safety for infinite life using the modified Goodman fatigue failure criterion.
