Problems on Stress-Strain State of a Three-Layer Cylindrical Shell with Transversally Soft Filler of Arbitrary Thickness under External Pressure and End Compression of Carrying Layers by Unequal Forces

摘要

We obtained the exact analytical solutions of problems on the stress-strain state of a circular three-layer cylindrical shell with transversally-soft filler of arbitrary thickness under the action of uniform external pressure and axisymmetrical unequal end forces applied to the carrying layers. We considered two variants of formulating the boundary conditions corresponding to two methods of strengthening and fixing the edges of real three-layer structures.
