Abstract
The stress state of three layer shell is considered in the condition when the external layers are elastic ones and symmetrically settled according to geometrical axis, and the middle layer has property according to non-linear viscoelasticity proposed by N.Ch. Arutyunyan. It is assumed that the stresses of middle layer are changed by non- linear relation along its thickness. For the obtaining of decisive equations it is used functions which define bending moments. For the investigation of stress–strain state, the system from four integral–differential equations for unknown functions is obtained. The numerical example is presented.
