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

摘要

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.
