| Abstract: | Based on the exact geommetric equations of deformed circular plates with axisym-metric deflections, the governing equations, in terms of the displacement of the middle plane, ofthermal elastic post-buckling of uniformly heated circular plates are deduced. By using the shootingmethod in conjuction with analytical cotinuation, the solutions of the post-buckling stute of the cir-cular plates, which depend on the thermal load peameter, are obtuined and some corresponding nu-merical results are given. |
