First and for most, I'm very proud to be one of this community members. One will learn a lot in different aspects.
aerostress82,
Thanks a lot for your explanation of natural frequency-center of gravity relationship. My chosen rectangular element has 3 degrees of freedom as shown in the attached...
GregLocock;
For the analysis results of case#1 structure(Plate only), there is no big worry about the small margin of error, since it could be rectified by either mesh refinement or different Gauss integration points used for evaluating the stiffness and mass matrices. My major concern is about...
Mr GregLocock, Thank you very much for your reply.
A word file titled as (Hussein) related to my thread is attached. Thanks a lot.

Hi there everybody,
I'm calculating the natural frequencies of an ordinary cantilevered plate and a cantilevered folded plate using Galerkin-based finite elements analysis. I prepared a matlab code for the analysis. For the ordinary plate, I got excellent results comparing to Ansys, but for the...
