Stress Concentration Factors: stepped_shaft_fillet_Dd1p1
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 | D d ratio | Kt bending (dimensionless) | Kt tension (dimensionless) | Kt torsion (dimensionless) | description | h r ratio | notes |
|---|---|---|---|---|---|---|---|---|
| stepped_shaft_fillet_Dd1p1 | 0.01 | 1.1 | 2.792 | 2.776 | 2.101 | Stepped round shaft shoulder fillet D/d=1.1 r/d=0.01 | 5 | D=large dia d=small dia r=fillet radius. Nominal: tension P/(pi*d^2/4); bending 32M/(pi*d^3); torsion 16T/(pi*d^3). |
