Section Modulus calculation and optimization

Report On Section Modulus Calculation Of Hood

INTERODUCTION : section modulus is the ratio of total moment resisted by the section to the stress in the extreme fiber.it gives on idea of how much load a structure can with stand if section modulud increase. the moment of resistance,and hence its load-bering capacity increases [s=l/y]

s=section modulus, I= moment of inertia, Y= Distance between the netral axix and and of the object , The Unit of a “section modulus” is (mm3)

PROCEDURE TO CALCULATE SECTION MODULUS :

1. for the hood design select the inter section curve command and take the curve in the O-Y

2.Figure in Project

3. Edit the sketch and using the project curve command project the intersection curve into the skecth plane
4. Using the quick trim curve command delete the inner curves of the outer and inner hood panel

Elastic section modulus- The elastic section modulus is used in the design application of structural member which determines the resistance to bending as within elastic limit as per the stress-strain curve. The failure of the component is considered in the elastic region.
