SCF_4

Rod with circumscribing u-shaped groove under bending

Function SCF_4 returns the stress concentration factor for a rod of diameter D with a circumscribing U-shaped groove. The rod is subject to bending moments.

Inputs:
D - the diameter of the rod ([m] or [ft])
t - the depth of the notch from surface (maximum normal distance between surface face and notch) ([m] or [ft])
r - the radius of the notch ([m] or [ft])

Example:
$Load Mechanical Design
$UnitSystem SI K Pa
D=0.24 [m]
t=0.025 [m]
r=0.075[m]
SCF=scf_4(D,t,r)

{Solution:
SCF=1.419
}
