Stresses in the filler material of three-layer cylindrical shell with orthotropic loadbearing
layer of structural fiberglass and lightweight filler type polyurethane foam were
investigated. The effect of elasticity of the filler material on the stresses in the bearing layers
of three-layered shells of rotation under the action of the ring load is shown. The given results
enable to estimate the error of the widespread assumptions regarding the cross noncompressibility
of the filler in the calculation of three-layered shells.
Keywords: three-layer cylindrical shell; orthotropic load; stresses. |
