翻译后摘要：这里提出的许多屈曲的例子的目的是给读者一个物理感觉壳屈曲。第一节简要介绍了两种屈曲形式：溃缩和双屈曲。第二节讨论的是壳体结构的非线性破坏，这种破坏是由于大挠度或大挠度和非线性材料特性共同作用而引起的。第3节给出了轴对称壳体的例子，其中失效是由于分叉屈曲。第四节提供了一些例子来说明边界条件和偏心载荷对旋转壳分叉屈曲的影响。第五节专门讨论圆柱壳的组合载荷和旋转壳的非对称载荷。第六节是关于环肋壳的分叉屈曲和倒塌，重点是圆柱壳。第7节包含棱镜壳和面板（即在一个坐标方向上具有恒定横截面的结构）屈曲的几个插图。第8节着重于预测屈曲载荷对初始几何缺陷的敏感性。第9节演示了旋转体的轴对称崩溃和分叉屈曲，这些旋转体由薄壳段和固体段的组合组成，壳理论不能以足够的精度应用于这些组合。
Abstract : The purpose of the many examples of buckling presented here is to give the reader a physical feel for shell buckling. Section 1 contains a brief description of two kinds of buckling, collapse and bifrucation. Section 2 concerns shell structures in which the cause of failure is nonlinear collapse due to either large deflections or to both large deflections and nonlinear material behavior. Section 3 gives examples of axisymmetric shells in which failure is due to bifurcation buckling. Section 4 provides examples that illustrate the effects of boundary conditions and eccentric loading on bifurcation buckling of shells of revolution. Section 5 is devoted to combined loading of cylindrical shells and nonsymmetric loading of shells of revolution. Section 6 is on bifurcation buckling and collapse of ring-stiffened shells with emphasis given to cylindrical shells. Section 7 contains several illustrations of buckling of prismatic shells and panels, that is, structures that have a cross section that is constant in one of the coordinate directions. Section 8 focuses on the sensitivity of predicted buckling loads to initial geometrical imperfections. Section 9 demonstrates axisymmetric collapse and bifurcation buckling of bodies of revolution that consist of combinations of thin shell segments and solid segments to which shell theory cannot be applied with sufficient accuracy.
