轴对称圆环壳的一个新解

Novel Solutions of Toroidal Shells Under Axisymmetric Loading

指出了现有渐近解的不足之处·本文统一用广义Ａｉｒｙ函数表示齐解和非齐特解的完全渐近展开，而现有的渐近解是用Ｂｅｓｅｌ或Ａｉｒｙ函数表示齐解，用Ｌｏｍｍｅｒ函数表示非齐特解的·本文所得到的新解是全域一致有效的，达到了薄壳的理论精度，且齐解和特解之间满足变动参数关系·事实上，本文给出了三个特解。

Several improvements are made for existing asymptotic expansions for the axisymmetric toroidal shells. The new expansions are numerically satisfaytory and satisfy the accuracy of the theory of thin shells. All of them are expressed in terms of generalized Airy functions, instead of Bessel or Airy function for the homogeneous and Lommel function for the particular solutions, respectively, as in the existing work. In fact, three particular solutions are given in the paper, one of which is just the solution obtained by Tumarkin(1959) and Clark(1963).
