 Distance between Notches d H - 2t
 Slab Thickness h << H

Stress Concentration Factors

Input data
H = 100 mm
t = 10 mm
r = 10 mm
Answer
 2.27  (2.41 in some literatures)
 
 2.83  (3.02 in some literatures)
 
Note that the stress concentration factors are calculated from experimental data using curve fitting, so only two decimal places are given.
