Section Modulus calculation and optimization
OBJECTIVE:
To Estimate the section modules of the mid section of hood and optimise section to a better value, with the help Nx Software.
SECTION MODULUS:
- Section Modulus is a geometric property for a given Cross-section used in the Design of beams or flexural Members.
- Other Geometric properties used in design include area for tension,radius of gyration for compression and moment of inertia for stiffness.
- Strength is nothing but,Capable of supporting greater loads, so higher Strength it has high capable Support greater loads.
SECTION MODULS S=I/Y
Where:
I: Moment of Inertia{MIn}
Y:Is the distance from the reference line to one of the external end of an object.

TYPES OF SECTION MODULUS:
There are Two Types Of section Modulus
- Elastic section Modulus
- Plastic Section Modulus

CALCULATION:
CASE-1
For my Hood Design MOI Values are,
Maximum Momentum Of Inertia:4.829516409e+06 [mm^4]
Minimum Momentum Of Inertia:1.523635635e+04 [mm^4]
Total Length of the Design:880.53 [MM]
=880.5/2
Y =440.25 [MM]
I=1.523635635*10^4
I=15236.35635 [MM^4]
S=15236.35635/440.25
S=34.608[MM3]
CASE:2
I have made some changes in my HOOD design and its section is given as follows,
Improvement section for my hood design,
Maximum Momentum Of Inertia:4.827568947e+06 [mm^4]
Minimum Momentum Of Inertia:1.53959087e+04 [mm^4]
Total Length of the Design:880.53 [MM]
=880.5/2
Y =440.25 [MM]
S=I/Y
S=1.53959087*10^4
S=15395.9087 [MM^4]
SECTION MODULUS
S=15395.9087/440.25
S= 34.970 [MM3]
RESULTS
CASE:1 S=34.608[MM3]
CASE:2 S= 34.970 [MM3]
