plate theory fixed edges
plate theory fixed edges
(OP)
Hello,
I am trying to determine the Internal moments, torques and twisting moments in a flat plate with fixed edges. I have taken a look at the biharmonic equation method and I am able to solve when the edges are simply supported but I am having trouble solving this equation when the edges are fixed. Can anybody give me some hints or atleast point me in the right direction as to how to go about this problem?
Thanks

I actually found this situation in roark's book but the solution given is max stress and max deflection.

I am a little bit confused of the solution to the biharmonic equation because it seems to me that if I use the Navier solution to the equation I will get the same answer no matter which boundary conditions I choose (simply supported or fixed edges). For example my solution to the boundary conditions of the simply supported case also satisfies those of the fixed edges case.

In the site below you might find the answer to your questions: rectangular plates are solved by using the energy method.
