This paper discusses stress-strain state peculiarities of a spherical thick-walled organic-glass shell under omnidirectional compression. It is pointed out that this stress-strain state is not linear and, consequently, cannot be described by “boiler” formulae.The paper compares analytical calculations based on the volume problem of elasticity theory versus FEM-based results. It has been established how weight and size of this shell depend on its acceptable stress.
