    A general theory for snap-through buckling of an open bimetallic shallow spherical shell under uniform temperature field is presented in this paper. It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement...

    A general theory for snap-through buckling of an open bimetallic shallow spherical shell under uniform temperature field is presented in this paper. It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement with earlier work by Wittrick.According to the selection of reference surface of coordinates as suggested by and Radkowski, the basic equations for a double-layered shell are first simplified in forms similar to those of classical shell theory. By analogy, the thermal effect is replaced by an equivalent edge-moment loaded uniformly along both boundaries of the shallow spherical shell. The problem is then solved according to Hu's simplified method, but with some vital modifications. From the results of numerical computations, the paper gives some rather interesting conclusions, which may be valuable in designing the elastic elements of various instruments in engineering.

    本文提出了有关开顶双层金属球面扁壳在均匀温度场作用下的稳定性的一般理论,它给出临界跳跃温度与壳体的物理、几何诸参数之间的相互关系,包括其开顶牛径大小也作为一个重要因素.文中并将它们绘成相应的实用曲线.在封顶球面扁壳的简化特例情况下,新理论似与早期wittrick的计算结果趋近一致. 根据与Radkowski建议的坐标参考面的选择方法,我们将双层壳体的基本方程首先简化成与经典壳体理论相似的形式.再通过比拟,以作用于球面扁壳内外边界上的均匀分布的相当边界力矩来替换温度效应.然后采用文献[6]的简化方法作了必要的改进来求解方程.从数值计算的结果,文中给出了一些有趣的结论,它们对于工程上各种仪表弹性元件的设计具有一定的参考价值.

    Investigations of the stability of truncated conical thin shells under torsional lord have so far been confined to the linear theory of small deflections, the methods used for determining the critical torque and the number of buckling waves being that of Ritz, the variational methods or simplified equations. These investigations are not perfect enough, while experimental studies are all the more wanting. This paper presents the experimental data of the critical torque and the number of circumferential buckling waves for 51 shells. Comparison is made with theoretical predictions. Description and some qualitative analysis of the occurrence and growth of the buckling waves observed and some other related phenomena are also presented.

    关于截锥薄壳在扭转载荷作用下的稳定性问题,已有的研究(例如文献[1,2])均只局限于小挠度线性理论范围,用Ritz法、变分法或简化方程的方法求出计算临界扭短和周向屈曲波数的公式.这些研究还不够完善,实验研究更为缺乏.本文给出了51个壳体的实验极限扭矩和周向屈曲波数,与现有的理论进行了比较,对观察到的屈曲波的发生与发展过程及其它一些现象作了描述和某些定性分析.

This paper reviews the general situation in this field and recommends two methods to illustrate this general theory, i. e. energy method and virtual work method. Here, the discussions of the elastic buckling and initial post-buckling behavior of cylindrical shells under hydrostatic pressure are made with virtual work method; and the curves of critical...

    Recently, considerable investigations have been made in the general theory of the buckling and the behavior of initial post-buckling of elastic structures[1.2]. This paper reviews the general situation in this field and recommends two methods to illustrate this general theory, i. e. energy method and virtual work method. Here, the discussions of the elastic buckling and initial post-buckling behavior of cylindrical shells under hydrostatic pressure are made with virtual work method; and the curves of critical pressure of cylindrical shells with small initial "bucklingwave imperfections" are given.
