Hi

I am working on "Buckling Analysis of composite materials by

ayleigh-Ritzmethod".

Can any one help me advising a MATLAB program regarding that?

I'm not familiar with "Buckling Analysis", but well with

Rayleigh-Ritz. In principle, you should determine an Action J, which

is an integral and minimize this integral with respect to some

variational parameters. In matlab it means you should use

"fminsearch"

You usually have linear combinations of trial functions (that

should obey the boundary conditions).

Example: Poisson's equ. in 1D have J=Int(L),

L=(1/2)*(dU/dx)^2-f(x)*U. With U(-a)=U(a)=0 you could take

U(x)=C0*(a^2-x^2). Integrating J and minimizing with respect to C0

gives you some result.
