Elastic Analysis:-

$Z_e = \frac{I_{NA}}{y_{max}} = \frac{\frac{πd^4}{84}}{\frac{d}{2}}$

[ $Z_e = \frac{πD^3}{32}$ ]

enter image description here

Plastic analysis:-

$Z_e = \frac{A}{2}[Y_1 + Y_2]$

= $\frac{πd^2}{8} * \frac{4d}{3π}$

$Z_e = \frac{d^3}{6}$

enter image description here

sharp factor:-

$\frac{Z_p}{Z_e} = \frac{16}{3π} = 1.64$
