Thin Plate modal analysis
I was doing modal analysis of a plate and comparing it to the analytical solution using Kirchhoff's thin plate theory.
Now what I know is that while using FEA the frequency will always be higher than the analytical cause it will be more stiffer cause of the number of the elements but here im getting less than the analytical.
Boundary conditions are u3=0 for all edges and one node u1=u2= 0 and another noed u1=0 to stop from rotation.
If anybody knows why this is happening.
Thanks
