Stress Concentration Factors: plate hole center
0.55 to 0.8
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 tension (dimensionless) | description |
|---|---|---|---|
| plate hole center | 0.55 | 2.128 | Flat plate central circular hole d/w=0.55 axial tension |
| plate hole center | 0.6 | 2.106 | Flat plate central circular hole d/w=0.60 axial tension |
| plate hole center | 0.65 | 2.089 | Flat plate central circular hole d/w=0.65 axial tension |
| plate hole center | 0.7 | 2.075 | Flat plate central circular hole d/w=0.70 axial tension |
| plate hole center | 0.75 | 2.063 | Flat plate central circular hole d/w=0.75 axial tension |
| plate hole center | 0.8 | 2.053 | Finite-width flat plate with central circular hole in uniaxial tension, d/W=0.8. d = hole diameter, W = plate width. Nominal stress on net section: sigma nom = P/[(W-d)*t]. |
