Bending Stress In Plate

Bending Stress In Plate

Bending Stress In Plate

(OP)
I am designing a plate that is fixed at both sides, the bottom, and free on the top.

I took this equation out of Rorkes Formulas for Stress and Strain--- sigma= -Beta*q*b^2/t^2--- where beta is dependent on the length of the plate divided by the heighth.

I found that the sigma max (flexural stress) was 113.5 psi.  Is this the maximum stress that can occur on the plate?  And is this per unit length of the wall or per area of the wall?

RE: Bending Stress In Plate

This should be the max stress, not per unit length, just the max stress.  This is a very conservative design because you can get 6 yield lines to form.

RE: Bending Stress In Plate

Roark has different beta constants for different positions on the plate ... if you check them all you should be ok.

RE: Bending Stress In Plate

Try the first site below (Plates -> Simple bending -> Rectangular -> 3 clamped, 1 free or 3 supp.,1 free) and compare the results with Roark.
