In this paper are presented integral expressions precise enough for computing the internal forces and vertical displacements of double curvature shallow shells under the action of a concentrated load over a certain distance from the boundary according to the moment theory of shells. In case of shallow shells of equal curvatures, these expressions can be easily integrated into formulae which are exactly the same as those given by E. Reissner, but for shallow shells of unequal curvatures, the solution is given...

In this paper are presented integral expressions precise enough for computing the internal forces and vertical displacements of double curvature shallow shells under the action of a concentrated load over a certain distance from the boundary according to the moment theory of shells. In case of shallow shells of equal curvatures, these expressions can be easily integrated into formulae which are exactly the same as those given by E. Reissner, but for shallow shells of unequal curvatures, the solution is given in the form of series composed of Thomson functions, the convergence of which is considered to be quite good in the ordinary scope of application (1 < k1/k2≤2). Furthermore, formulae for the internal forces and vertical displacements of shallow shells of equal curvatures under the action of circular line loads and circular ring loads as well as their exact values at the point of a concentrated load for shallow shells of unequal curvatures are also given in the paper.

本文从杜庆华各向同性线性理论出发,经过变换把基本方程简化为相当于一个单层薄板的方程和三个弹性地基上的薄膜方程.指出了杜庆华各向同性线性理论与Hoff和Reissner理论之间的主要差别为相差一个或两个弹性地基上的薄膜方程.导出了均布载荷和集中载荷作用下四边简支板挠度的近似公式,并按几种理论进行了分析比较.此外,提出了1948年Reissner型线性理论有关挠度的边界条件.在夹层板的合成内力的计算中,发现弯矩与单层板的弯短相同.

In 1939, the importance of the nonlinear features in the shell buckling problem was first pointed out in a most spectacular manner by Von Karman and Chien, but the mathematical difficulty is so great that progress has been slow after the first attempts. According to our experience, we should face the difficult barrier of solving nonlinear partial differential equations and an effective, simple, accurate method is required. With this in mind, we suggest the modified iteration method. four cases are considered...

In 1939, the importance of the nonlinear features in the shell buckling problem was first pointed out in a most spectacular manner by Von Karman and Chien, but the mathematical difficulty is so great that progress has been slow after the first attempts. According to our experience, we should face the difficult barrier of solving nonlinear partial differential equations and an effective, simple, accurate method is required. With this in mind, we suggest the modified iteration method. four cases are considered to verify it. Here is one of the cases in which nonlinear stabilities of thin circular shallow shells under actions of axisymmetrical uniformly distributed line loads are considered. As special cases, we have also investigated large deflections of plates under the same loads. All these results are presented in such a form that direct application in design is possible. Two stability curves coincide with the experimental results given by D. G.Ashwell and Chien Wei-chang. The results have also been compared with several other writers'.

本文对边緣簡单支承在对称綫布载荷作用下园底扁薄球壳的非线性稳定問題进行了研究。用我們提出的修正迭代法求出了决定上下临界載荷的二次近似的解析公式並画成曲綫以供工程应用。作为特殊情况,我們附帶地得出了边緣簡单支承中心集中载荷作用下的园底扁薄球壳的非綫性稳定問題,边緣簡单支承在对称线布載荷作用下和中心集中載荷作用下的园板大撓度問題的解。所得結果和两种不同的实驗进行了比較,理論值和实驗值相当符合。对于中心集中載荷作用下的园板大挠度問題,我們的結果和文献[16]用摄动法得到的完全相同。
