Stress Concentration Factors: shaft_keyway_sled_annealed
Stress concentration factors (Kt) for common shaft and plate geometries — stepped shafts, grooves, holes, keyways per Peterson's and Shigley's
| geometry type | r d | Kt bending (dimensionless) | Kt tension (dimensionless) | Kt torsion (dimensionless) | description | notes |
|---|---|---|---|---|---|---|
| shaft_keyway_sled_annealed | 0.1 | 1.3 | 1.3 | 1.3 | Sled-runner (woodruff) keyway annealed shaft r/d~0.10 | Sled-runner profile has lower Kt due to smooth runout. Both bending and torsion Kt=1.3 annealed. |
