boundary conditions
(OP)
Hi
Just wanted to ask i want to simulate a thin plate and determine the buckling load from the eigenvalue. The eigenvalue i have determined is very high to the power of 9. Wanted to ask its a simply supported plate, what should be the boundary conditions.
Thank You

RE: boundary conditions
Can you describe your problem in a little more detail, please? An eigenvalue for a buckling problem with a result order-of-magnitude 10^9 is very bizarre.

Tell me more about this "shell load" that you are applying. That may have something to do with this.
RE: boundary conditions
The initial boundary conditions which i inputted to get the high value for the eigenvalue were:
A) U3 ticked on all side
B) U2 ticked on two parallel sides
C) U1 ticked on one of the parallel sides
D) then shell edge load on the opposite side of side in C
Are these boundary conditions applied correct?

A picture would really help. I can infer the orientation of your plate (sort of), but I can't say for certain.

Nevertheless, you calculated a value using FEA of 2.09 compared to a theoretical value of 1.58. Is you result independent of the mesh (have you performed a mesh-convergence study)?
