Answer:
Shape factor
Explanation:
Shape factor is the ratio of maximum plastic moment to maximum elastic moment.Shape factor is denoted by K.
Shape factor can be given as
[tex]K=\dfrac{M_p}{M_y}[/tex]
[tex]K=\dfrac{\sigma _yZ_p}{\sigma _y Z}[/tex]
[tex]K=\dfrac{Z_p}{ Z}[/tex]
For a solid rectangular section made from ductile material shape factor is 1.5 .
