摘要: 基于von K×rm×n薄板大挠度方程,本文研究了经受非均匀轴对称温度场的环形薄板在多种边界条件下的热屈曲问题.采用分析与计算相结合的方法着重讨论了热屈曲的线性化问题,获得了反映环板失稳特征的稳定边界.

Abstract: On the basis of Von Karman equations, the thermal-buckling of thin annular plates subjected to a field of non-uniform axisymmetric temperature and a variety of boundary conditions is discussed. The linearized problem is analyzed and stability boundaries which characterize instability of oplate are obtainedby means of numerical and analysis methods.
