Abstract

The article presents the derivation of equations describing the pre-buckling behavior of three-layer rods in the presence of shear deformation and creep of the middle layer. The test problem for a rod with a filler made of polyurethane foam is solved. A technique has been developed for calculating the critical time under loads which values exceed the long critical ones.
