Section Modulus calculation and optimization

Section Modulus Calculation using NX CAD

• What is Section Modulus?

1. Section Modulus is a geometrical property used to design beams and other load-bearing components.
2. It may also be defined as the ratio of Moment resisted by section to the outermost fibre of the section.
3. Section modulus defines the strength of the component i.e the higher the SM the higher the structural rigidity.

Section modulus can be calculated by using the formula -

S=I/y

S - Section Modulus

I - Moment of Inertia

y - Distance from the neutral fibre.

Procedure -

• MOI (Max) - 832523.2431 mm^4
• MOI(Min) - 3717.420993 mm^4
• y - 488.31/2 = 244.155 mm
• S - 15.22565990047306 mm^3

To improve the moment of inertia value and maximise the value of Section modulus we decrease the value of the embossed region by 1 mm

• MOI(max) - 834462.9102 mm^4
• MOI(min) - 3780.926404 mm^4
• y - 244.155 mm
• S - 15.48576274907333 mm^3

Conclusion -

From the above observation, we can see that the value of MOI increases by changing the depth of the embossed region and by increasing the area.
