Section Modulus calculation and optimization

                            Section Modulus calculation and optimization

AIM:

   To Calculate the section Modulus of the previously designed Hood to Examine its Strength and also optimizing the design to see the difference in the bending Strength of the Hood.

SECTION MODULUS:

The Section Modulus is Geometric property of a structural cross section that measure its resistance to the bending. it is crucial parameter in structural engineering and design, especially in relation to beams and other components subjected to bending moment.

The higher the Section Modulus, the more resistant a section is to bending and deflection. Engineers use this property to assess the Structural performance of beams and ensure they can withstand applied loads without experiencing excessive bending or defamation.It plays a vital role in the design and analysis of structures, helping engineer select appropriate material and dimensions to meet specific Strength and Safety Criteria.

MATHEMATICALLY,

                              Section Modulus is

                                  S=I/Y

Where,

       S= Section Modulus.

       I= Moment of Inertia (Unit mm^4).

       Y= Distance from Neutral Axis to the extreme end.

                   (Unit of Section Modulus is mm^3)

First Design Study:

The Intersection is taken from the Hood Design, then I create a seperate Sketch and project the Intersection to the Sketch then by using Section Inertia Analysis we get the Moment of Inertia.

                    Moment of Inertia(max)= 8.936765*10^7(mm^4),

                    Moment of Inertia(min)= 3.013806*10^5(mm^4),

                                                         Y = 879.46/2

                                                         Y = 439.73

                                                          S=I/Y

                                        S= 3.013806*10^5/439.73

                                                 S=685.37mm^3

Design Optimization:

 To Examine the Section Modulus of the Hood Design by changing design by increasing the Depth of Inner panel by 0.5mm.

                                       Moment of Inertia(min)= 8.920119*10^5(mm^4),

                                                     Moment of Inertia(min)= 3.052598*10^5(mm^4),

                                                         Y = 879.46/2

                                                         Y = 439.73

                                                          S=I/Y

                                                          S= 3.052598*10^5/439.73

                                                          S= 694.19mm^3

RESULT:

So, After Calculation as we can see the difference in Moment Of Inertia,and Section Modulus is Changing aswell by Changing the Design in Hood.
