CHARTS OF THEORETICAL STRESS-CONCENTRATION FACTORS

ROUND SHAFT WITH TRANSVERSE HOLE IN TORSION

Nomenclature:
T = Loading torque
D = Shaft diameter
d = Hole diameter
J = Bar polar moment of inertia
c = Distance to shear element

Relationships:
--------------
J / c = 3.14159 * D^3 / 16 - d * D^2 / 6
