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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
