The behavior of viscoelastic hemispherical shells was investigated under internal blast loading. It has been revealed in the process of calculation-experiment research of dynamic viscoelastic properties of structural polymeric materials that glassy polymers change sharply their viscoelastic characteristics. Unlike to mechanical glass transition to glassy state glassy polymers showed ability to transfer into the high-elastic state as a result of elastic energy dissipation.

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.
