 Thickness of Box Beam h  
 Radius of Inside Corner r  
 Inner Hight and Width of Boxed Beam a >> h
 Hight and Width of Boxed Beam H a + 2 h >> h

Stress Concentration Factor

Input data

h = 10 mm
r = 10 mm
Answer
 1.25
 
 
Note that the stress concentration factors are calculated from experimental data using curve fitting, so only two decimal places are given.
