Section Modulus calculation and optimization

Aim :- Finding the section-modulus of the hood and improving by increasing the strength of the hood by alteration. perfroming the case study.

SectionModulus :- the geometry of thge given cross-section used in the design of beams etc.. also used in rdius of gyration for compression. the relationship depends on the shape of the models. two types of section modulus are 1. plastic 2. elastic section modulus.

• section modulus is calculated by using the formula S= I/Y

where , S= section modulus. I= moment of inertia . Y= distance between extreme ends.

The distance from the axis to the two ends -

Case - 1 :-

Case -2 :-

• the section modulus calculations are showed in the below images. the curve is off-set to 0.5mm in downwards direction to increase the strength.

Result :-

• Case -1 S= 522.997 mm^3
• Case -2 S= 5460.09 mm^3

the difference between the case-1&2 is the variation in the the distance between the hood inner and outer panel.

the distance varying is 0.5mm.

inconclusion ,increase in the distance has improved the strength of the hood .
