| 内容記述 | A set of nonlinear differential equations based on the finite deformation theory in the two-dimensional shells has been solved by assuming a specified deflection mode because of the difficulty to obtain their exact solution ; however, the particular deflection mode assumed has a great effect on the buckling load, giving considerably higher theoretical values than experimental values, as noted in he previous paper. From the above circumstances, the progressive approximation method was applied to the snap bucking problem under uniform pressure of a shallow spherical shell segment having small value of α=αβ^2/t(a ; radius, t ; thickness, 2β ; angle of opening) and a more precise and reasonable solution could be obtained by means of a comparatively simple mathematical treatment. That is, much lower initial buckling loads were obtained with the deflection mode which varied reasonably with the variations of load and deflection, verifying the appropriateness of this method. | |||||||
