CHARTS OF THEORETICAL STRESS-CONCENTRATION FACTORS

PLATE LOADED IN TENSION BY A PIN THROUGH A HOLE

Nomenclature:
sigma0 = stress without concentration factor
F = Loading force
w = Plate width
d = Pin diameter
t = Plate thickness
A = Plate stress area

Relationships:
--------------
A = (w - d) * t
sigma0 = F / A

When clearance exists, increase K_t 35 to 50 percent.
