Section Modulus calculation and optimization

Section Modulus is a geometric property for a given cross section used in design and it is also a ratio between the moment of inertia of the section and elastic modulus of the section.

steps followed to calculate section modulus.

1. created a intersection in inner and outer panel.
2. offseted a plane and created a sketch and projected all outer profile of the intersection and joined all the openings.
3. smoothened the sketch by using smooth curve option
4. filled the section by using surface fill command.
5. calculated the moment of inertia of the section by using insertia tools 2D.
6.converted the values from meter to mm.
7.selected the lesser value between both values of moment of inertia.
8.calculated elastic modulus (Y) by measuring between neutral axis and extreme end of profile.
9.calculated section modulus (s) by finding ratio between the I and Y.
10. optimized the section my reducing the pocket size and emossing profile.
and calculated same for optimized section.

Conclusion: By changing the emossing profile and reducing the pocket size the section modulus has been incresed.
