Shape Factor

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Shape factor, abbreviated as k, a dimensionless number, is used in structural it is the strength of the shape no matter the scale for a given load, bending, torsion, or twisting.

 

Shape Factor formula

\(\large{ k = \frac{Z}{S} }\)   

Where:

\(\large{ k }\) = shape factor

\(\large{ S }\)  = elastic section modulus

\(\large{ Z }\) = plastic section modulus
