Plastic modulus of section Zp for a rectangular section of width b and depth d is given by:
Ab * d^2 / 6
Bb * d^2 / 8
Cb * d^3 / 12
Db * d^2 / 4
Explanation
Plastic section modulus Zp measures ultimate bending capacity of a cross section in plastic design. For a rectangular section of width b and depth d, Zp = (b * d^2) / 4 (compared to elastic section modulus Ze = b * d^2 / 6).
