CHARTS OF THEORETICAL STRESS-CONCENTRATION FACTORS

GROOVED ROUND BAR IN TENSION

Nomenclature:
sigma0 = stress without concentration factor
F = Loading force
D = un-grooved bar diameter
d = grooved bar diameter
r = groove radius
A = Bar cross-sectional area

Relationships:
--------------
A = 3.14159 * d^2 / 4
sigma0 = F / A
