Plastic Section Modulus Rectangle

Elastic and plastic section moduluoments for an i.
Plastic section modulus rectangle. A geometric property used in the design of beams is called as section modulus. In that case the whole section is divided in two parts one in tension and one in compression each under uniform stress field. The plastic section modulus for a rectangular cross section can be determined by multiplying each section half e g the shaded area shown in figure 1 50 by the distance from its centroid to the centroid for the whole section.
Using the structural engineering calculator located at the top of the page simply click on the the show hide calculator button the following properties can be calculated. Unequal i beam geometric properties. A section modulus is the property for a cross section used in the designing of beams.
Zx b h 2 h 4 b h 2 h 4 bh2 4. Z elastic section modulus in 3 or mm 3. The plastic section modulus is similar to the elastic one but defined with the assumption of full plastic yielding of the cross section due to flexural bending.
Online rectangle property calculator. Section properties radius of gyration cases 1 10. Section modulus of a rectangle calculator.
The plastic section modulus is used to calculate the plastic moment m p or full capacity of a cross section. Enter the breadth and height of the inner and outer rectangle to find the section modulus. Plastic section modulus and elastic section modulus are related by a shape factor which can be denoted by k used for an indication of capacity beyond elastic limit of material.
In this calculator the section modulus of the rectangular tube is calculated. Sign in to download full size image figure 1 50. The plastic section modulus is used to calculate the plastic moment m p or full capacity of a cross section.
