Stress concentration factors due to typical geometric discontinuities for shaft design by numerical simulationStress concentrations are caused when there are geometric discontinuities. Step shoulders with fillets, key seats and retaining-ringgrooves in shafts are the typical geometric discontinuities. In most textbooks of mechanical component designs, the stressconcentration factors for the step shoulders with different fillets in shafts are fully explored and presented by sets of stressconcentration factor curves. The preliminary stress concentration factors of retaining ring grooves are also provided. Key seats aretypical features of shafts, but no related stress concentration factor curves due to key seats are listed and shown. No full set ofpreliminary stress concentration factors due to key seats for shaft design is presented. When I discussed shaft design with mymechanical students in mechanical component design course, students always felt lost because no recommendation or curves for thestress concentration factors due to key seats and retaining-ring grooves are provided for conducting shaft design. In this paper, thestress concentration phenomena due to end-mill key seats, the sled runner key seats, and retaining-ring grooves on different nominalshaft diameters have been fully and systematically explored by numerical simulation, that is, Finite Element Analysis. A set of stressconcentration factor curves due to key seats and retaining-ring grooves will be presented. The results presented in this paper willgreatly facilitate mechanical students to conduct the shaft design.
