CHARTS OF THEORETICAL STRESS-CONCENTRATION FACTORS

GROOVED ROUND BAR IN BENDING

Nomenclature:
sigma0 = stress without concentration factor
M = Loading moment
D = un-grooved bar diameter
d = grooved bar diameter
r = groove radius
I = Bar 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
