| 内容記述 | The nonlinear snap buckling problem of curved beams having small curvature due to external pressure, in which it is possible to obtain the exact solution, was taken up as an example to discuss the questions (1) whether or not the approximate methods usually used in the analysis of nonlinear elastic problems are proper to define the buckling load, and, (2) whether or not an unsymmetrical deflection might give a lower buckling value, as pointed out previously. The comparison of the exact solution with approximate solutions showed that the assumed deflection mode has a great influence on the buckling load. Further, the analytical result that the buckling loads obtained in the unsymmetrical mode are lower than those in symmetrical modes is found to be true only within the degree of precision of the approximate solutions themselves. The reason is that, the symmetrical deflection mode derived from the exact solution of the nonlinear equation gives the minimum buckling load. These analytical results seem to suggest the need for scrupulous attention to the assumed deflection mode in approximation method necessary for two-dimensional problems, such as problems of plates and shells. | |||||||
