CHARTS OF THEORETICAL STRESS-CONCENTRATION FACTORS

ROUND SHAFT WITH SHOULDER FILLET IN BENDING

Nomenclature:
sigma0 = stress without concentration factor
M = Loading moment
D = un-filleted shaft diameter
d = filleted shaft diameter
r = fillet radius
I = Shaft cross-sectional moment of inertia
c = Distance to bending moment element

Relationships:
--------------
c = d / 2
I = 3.14159 * d^4 / 64
sigma0 = M * c / I
