极正交各向异性环板的热屈曲

Thermal buckling of polar orthotropic annular plates

基于 Von Karman薄板大挠度理论 ,通过位移形式的控制方程 ,分析和讨论了极正交各向异性环板的热屈曲问题 .考察了材料弹性常数和热膨胀系数以及不同温度场对板的临界温度以及过屈曲行为的影响 。

Based on Von Karman theory for large deflections of thin plate, the thermal buckling of polar orthotropic annular plates is discussed by using the governing equations in terms of displacements. The effect of the modulus of elasticity, the thermal expansion coefficients, and different temperature distributions on the critical buckling temperature and post buckling behavior of plates are examined.
