Section Modulus calculation and optimization

section modulous in hood design is a comparative study to increase resistance towards crash of any vehicle.

section modulous:ratio of area of MOI about neutral axis to the distance of outer most fibre from neutral axis.

units are mm3 or m3

neutral axis: axis where there wont be any tension nor compression.

area of momemt of inertia:area where it will depict resistance offered by cross section towards bending

case 1

s=I/Y

=3.10510655x10 to power 5/[876.2/2]

=707 mm3

in case 2:[ we havw offseted the emboss length to 0.5 mm]

s=3.157562040x 10to power 5/[876.2/2]

=730.42 mm3

Result:Strength of material is directly proportional to the moment of interia, thus increasing the sectional area increase the increases strength of component.

Thus sectional modulus for hood design is calculated and optimized design is also done to increase the section modulus of the hood.
