Concerning the critical load for an orthotropic cylindrical shell with a viscoelastic core

The problem of determining the critical load for a cylindrical shell with a viscoelastic core is considered. An expression for the critical load under quasistationary loading is obtained on the basis of a generalization of the Winkler hypothesis.Institute of Polymer Mechanics, Academy of Sciences of the Latvian SSR, Riga.
