This paper presents the problem of calculating the stress state of the composite cylinder shell under the effect of temperature on the basis of the theory of high-order shear strain according to the analytical approach. In this paper, the three-dimensional equations in the theory of nonlinear elasticity of the shell under the effect of heat load are established into two-dimensional nonlinear equations for the cylindrical shell by using the method of transformation and decomposition. product of the displacement field into a series of polynomial functions according to the shell thickness. On the basis of the obtained equations, a system of balanced equations according to the displacement field and the corresponding boundary conditions for the case of analysis of displacement into a cubic polynomial is given. The calculation program is set up and the verification is compared with the published results. The survey on the stress state of the composite cylinder shell under the effect of heat is presented.
