I am trying to write a finite difference code in Matlab to solve the Kirchhoff's plate equation. So far, I have been able to generate the biharmonic/bilaplacian operator matrix. However, I am struggling with how to impose the boundary condition. I would be glad is someone can help explain how to achieve this.
I have taken the liberty of attaching here an m.file I found on the net prepared by
I. Danaila, P. Joly, S. M. Kaber & M. Postel. The task is to use this to generate the biharmonic operator matrix of the kirchhoff's plate equation (which I also have taken the liberty to attach here as well). Thanks
Dear Yakubu.
my grasp of your problem is smattering.I hope you'll explain this matter a bit more!
You may use fictitious point method, by defining an point of variable matrix and via discritizing conservation equation in boundary and use this nes equation for evaluating you fictitious point.
if this is near to your problem , you may find classified methods in GERALD advaned mathematic book
regards
Dear Mahdi
Thanks for your prompt response. For the sake of clarity, I have taken the liberty of attaching some documents hoping to throw more light on my challenges.
