Hi all:(adsbygoogle = window.adsbygoogle || []).push({});

I am fresh to engineering and have basic question.

I have a 100 inch length and 40 inch wide & 6 in depth plate , it has honeycomb structure what I mean 0.125 inch face sheet of aluminum on either side and rest (6-.125*2)is honeycomb made of alumnium.It is supportted on 4 sides.Pressure load on this is 75 psi. I need to calculate the stiffness of this plate for this load.

I know the deflection from test which is 3 inch at the center for this load.

Once I know the deflection then stiffness would be total load on the plate which is (100*40*75=300000 lbs) devided by deflection, which is 300000/3=100000lbs/in.

Do u think I am right in this.Please give some suggestions.

But i am wondering how come it is so stiff (100000 lbs/in)

thks
