SF_18
Function SF_18 provides the shape factor ([m] or [ft]) for a thin plate completely buried in a semi-infinite medium and parallel to the surface.
Inputs:
w = depth of strip below surface ([m] or [ft])
b = width of strip ([m] or [ft])
L = length of strip ([m] or [ft])
Example: SF = SF_18(w, b, L)

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo w, b, L, SF units=m
w = 0.5 [m]
b = 0.1 [m]
L = 1 [m]
SF = SF_18(w, b, L)
{Solution:
SF = 1.757 [m]}
