temperature dependent properties

I would like to share with you my first paper in a SCI journal: doi:10.1088/0965-0393/21/6/065017

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 ?
