Dear all

I really appreciate if someone tell me about the industrial applications of annular FGM plates.

Best regards

Dear all

I'm working on the thermal buckling analysis of a radially graded annular FG plates with temperature dependent properties.

The results show that the temperature dependent thermal buckling loads are greater than those of the temperature independent, but I have expected for vice vesa results!

Can anyone explain it ?

I'm looking for the thermo-mechanical properties of aluminum, such as  Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :

E=E₀(1+E₁*T+E₂*T^²+E₃*T^³)  ;  T: temperature in K

I am working on thermal buckling of annular FGM plates using the DQ method in FORTRAN. The results show that for simply-simply edges, the nonlinear thermal buckling loads are greater than those of eigen buckling loads. But for clamped-clamped edges, as it may be expected, the nonlinear buckling loads are under estimate, i.e. they are lower than eigen buckling loads.Why?

Is it possible that the nonlinear buckling analysis gives us an over estimate load ?
