G'Day Everybody, I am computing buckling of rectangular(a*b) specially orthotropic composite. The boundary conditions are clamped-clamped at the opposing loaded edges and the other two edges are free (also known as CFCF). After having the boundary conditions and the governing differential equation I to need to assume the deflection of the buckled shape in order to apply Rayleigh Ritz Method. At this point I would like to know if anybody can tell me that the following shape function is correct or not:
w(x,y)=A*(1-cos(2*pi*m*x/a)
,where:
A: is to be determined at afterwards
m: Natural for Buckling
or should be the following, du to the modeshape in y-direction(w
=A):
w(x,y)=A*(1-cos(2*pi*m*x/a)*A
I assumed it to be correct but the following calculations where simplified so much that I am not sure anymore.
Any help would be greatly appreciated.
Thanks
Sam
