Excerpt from Non-Linear Deflections of Shallow Spherical ShellsConsider a thin, hollow sphere of wall thickness 2b and mean radius R loaded by a uniform external pressure p directed towards the center. It is observed experimentally that as the pressure increases from zero, the shell apparently deforms by contracting into a smaller sphere. This mode of deformation continues until some critical value of the pressure is reached. At this value the shell suddenly jumps, or buckles into a non-spher ical buckled state consisting of a round, rotationally symmetric, inward dimple of small solid angle at some point on the surface of the shell, while the remainder of the shell remains apparently spherical.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
