Section Modulus calculation and optimization

SECTION MODULUS:- Section modulus is the ratio of the moment of inertia to the neutral fiber distance which unit is mm3.

S = I/y

S = Section Modulus

I = Moment of Inertia

y = distance between the neutral axis and the extreme end of the object

1.The first section modulus calculate of the car hood without optimization of the model.

With the help of inetria command we have calculate the minimum and maximum inertia

MIN (I) =241912.479 mm4

MAX (I) =86583616.155 mm4

Mid distance ( Y) =226.287

Now the using the above formula

MIN section modulus (S) =1069.0516 mm3

MAX section modulus (S) =382627.4428 mm3

2. Now we have optimize the above model and now again calculate the section modulus.

MIN (I) =264455.329 mm4

MAX (I) =91199365.118 mm4

Mid distance ( Y) =226.287

Now the using the above formula

MIN section modulus (S) =1168.67221 mm3

MAX section modulus (S) =403025.2074 mm3
