Thermal Post-Buckling of FG Circular Plates Under Transversely Point-Space Constraint

Y. SUN, S. LI

Abstract


Axisymmetric thermal post-buckling of FG circular plates with immovably clamped boundary and a transversely central point space-constraint were studied. Based on von Karman’s plate theory, governing equations for the problem in terms of the displacements were established. By using shooting method, before and after the plate contacted the point space-constraint, the changes in the characteristics of the deformation and the internal forces of FG plates were discussed. The effects of material gradients and non-uniform temperature rise parameters on the thermal post-buckling behaviors of FG circular plates were analyzed.
